A friend of mine sent it to me and it seems like an interesting option now that hardware pricing has gone insane?
malux85 6mo ago
Eeek, I can't imagine what this is like if it scales. What happens to the fire risk when theres 20,000 laptops with aging batteries all sitting together? I hope they take the batteries out, however many laptops use batteries to smooth out power fluctuations. Laptops aren't designed to be servers - peg your laptop CPU and GPU at 100% and see how long it lasts, I've done this before and the answer is about "2 months", yep sure, this effort isn't targeting that workload, but how many bad apples does it take to start a fire? In their page they say "kubernetes server - no problem" kubernetes DOES keep the CPUs busy, not pegged, but busy enough so that they wont step down their frequency. I admire the effort to reuse old tech, but boy oh boy would I not want to be a sysadmin here!

  My old Lenovo t420 has been running 24/7 pegged as a multi-camera DVR since 2011, no issues whatsoever. Of course the battery is removed, but I don't see many decent laptops struggling running under load for prolonged periods.

  I worked for a place that did something akin to this in the early 2010s. Someone figured out how to add 32-bit company laptops to the virtualization cluster (likely because they were using one as a stand in for a server that at the time would have been in the works but not yet purchased) and so once that work had been incurred they just kept "retiring" unserviceable company laptops to the cluster. Imagine a standard wire metro-rack crammed in a telecom closet beside a normal server rack. Now imagine that metro rack literally full of Toshiba Satellite Pro's from about 2005-9. The cluster hosted virtual machines for testing. No fires, no hardware problems. No special cooling other than the mini-split that was in the closet to cool the server rack. They just kept trucking. But modern hardware is much more high strung and I don't doubt you'd have weird failures. Edit: Back then VMs were how things were done and RAM was seemingly always the bottleneck by a mile, so the cluster did add up to a meaningful amount of extra performance compared to not having it.

  - martheen 6mo ago
    This particular project imply a financial commitment (it's not like you can walk to the data center right now with random assortment of laptops to be setup today without reserving a rack for a month or so), using a free hosting mean they didn't even spend the minimum.

Say what you want about an old laptop, they sure are a lot faster than a $150/mo azure VM. And to be clear, I mean a _LOT_ faster.
- hsbauauvhabzb 6mo ago
  That’s saying a lot about azure, not the laptops.
- kingstnap 6mo ago
  I looked it up for specifics. Right now the closest I can see is that $121/mo gets you 4 Xeon Platinum 8370C cores and 16GiB of RAM [0] (storage not included!). Somebody Geekbenched that config here [1] 1274 single core 4256 multi core. Thats kinda terrible ngl. A mini pc with last gen mobile parts like Ryzen 5 7640HS gets 2610 single and 10768 multi core [2].

    I feel like Azure and AWS are both getting worse. I logged into a VM I haven't used in some time and was immediately shocked at just how slowly it rendered even the most basic UI elements.
- notpushkin 6mo ago
  All the big 3 cloud providers suck if you use them purely as VPS. I’ve tried AWS Lightsail (basically, slightly cheaper EC2) and it’s so much slower than what I’d expect from a similar spec VM from a normal hosting provider. Hetzner, DigitalOcean, OVH, Vultr are some of the better-known ones. Personally, I’m very happy with SSD Nodes. Paying $90/yr for a 4 vCPU¹ / 16 GB / 320 GB SSD, had some downtime exactly once in two years (they’ve had to switch their IPv4 space in Tokyo). Affiliate link: https://ale.sh/r/ssdnodes https://ale.sh/r/ssdnodes [1]: Intel Xeon E5-2650 v4 (4) @ 2.199GHz – not great, I know, but to reiterate: that’s for $90 a year.
donohoe 6mo ago
Great idea but is this real? Its a page hosted on CLoudFlare's "pages.dev" service. Their method of contact is a Google Form which does have an email address on this domain "CoLaptop [dot] com", but that as a web address does not work. I'm not sure they have their act together.

lots of proxmox clusters in basements run on old laptops. my pile of t480s beats any cloud vm (except when my ISP goes down).

I presently use an extra laptop to compute and run for batch jobs. Easy, fast.

Yeah for dev purposes perhaps. Production would be another story.
pinkmuffinere 6mo ago
> Your old laptop packs more CPU power, RAM, and storage than their entry-level offerings - and with us, you'll pay just €7/month for professional hosting This is basically the same price as the cheapest options on Hetzner: https://snipboard.io/C9epWo.jpg https://snipboard.io/C9epWo.jpg. Sure my old laptop does have more RAM and a bigger SSD, but I bet it's also less reliable than Hetzner's servers, and is likely to suddenly die some day. So is the tradeoff really worth it? It's hard for me to believe that this is a genuine improvement for most things. The only definite winning case I can think of is if I have a process I want to run, but I don't care if it just suddenly stops working. But when would that ever be the case? and to save a couple dollars per month? Edit: Maybe this is what github is doing :P
- foobarian 6mo ago
  Not sure how Hetzner works, but do they have IDRAC type access to their servers and/or remote hands available to fix stuff? Guess you'd be on the hook for that sort of thing here, making the Hetzner price more appealing if they do include that kind of functionality.
  - folmar 6mo ago
    For physical machines of course yes. The linked one is VPS, so all trouble fixing is easier.
- QuantumNomad_ 6mo ago
  > I bet it's also less reliable than Hetzner's servers, and is likely to suddenly die some day I’m a happy Hetzner customer but I have had servers that I rented from them die a couple of times. I rent physical servers from them that have been previously rented to other customers. At some point hard drives fail. However, I have solid backup setup in place (ZFS send and recv to other physical hosts in different physical locations) with that in mind, so I haven’t lost data with Hetzner. But if I naively did not have any backup then data would have gotten lost a couple of times.

      I would like to put my Raspberry Pi Pico in colocation, would it work?
      - QuantumNomad_ 6mo ago
        There are a number of places that colocate normal Raspberry Pi. https://lowendbox.com/blog/little-machines-in-big-datacenters-where-to-host-your-raspberry-pi/ https://lowendbox.com/blog/little-machines-in-big-datacenter... I am sure that some of them either already colocate Pico ones too, or are willing to do so if asked.
        gzread 6mo ago
        The Pi Pico doesn't have networking capabilities, so that would be silly. You're probably thinking of the Pi Zero.

  They can't profit from your garage.
- arm32 6mo ago
  In theory—the data center they'd put your laptop in has a much faster, and more reliable, internet connection than your garage.
  - wltr 6mo ago
    That surely depends on a country. Data centre is still better in theory. But in practice, I have very little imagination to use a gigabit connection all to myself.
- kube-system 6mo ago
  Colocation has reliable power, reliable environmental conditions, and internet connections that are better suited for running servers.
burnt-resistor 6mo ago
Hmm, there's might something to this: + The usual limiting factor in data centers is power, so laptops could be more optimized for greater cycle efficiency per power than comparable old servers. + Laptops are generally compact and so achieve greater rack densities than individual co-lo servers. I'm thinking about 34 or 51 laptops could be stored in 9 or 10U either 2 or 3 rows deep by 17 wide. + Shipping a laptop to a co-lo data center is cheaper than a 1U server. ~ Reusing electronics saves e-waste and reduces unnecessary consumption, either old servers or old laptops. - Laptops lack ECC RAM. - Laptops typically don't use nearly as fast CPUs or RAM as contemporaneous servers. - Laptops are limited in their storage options. - Laptops lack remote, lights-out management of real servers. - Repairing old failed laptop components is more difficult than old servers. ~ Old laptops tend not to have usable batteries, so there's unlikely to be much an inherently distributed battery backup capability. - Old laptop batteries of various origins could be a li-ion NMC fire hazard at scale. ~ Reusing old stuff at any sort of scale would prefer standardization, and it's sometimes difficult to amass many of the same discontinued model. Conclusion: Do it if it works for you. It's kinda cool.
- saltcured 6mo ago
  I think it's one of those ideas that only works with nostalgia or hoarding impulses to support it. I think normal virtualization approaches are far more power efficient, at a fleet level, than any kind of cluster of laptop scenarios. You can pile in the cores and amortize the costs of memory controllers etc. over a large set of guests. It is a funny way to get features of both worlds. One reason to want colo (rather than VMs) is for predictability, but laptops still give you the funny throughput problems, because of thermal throttling instead of competing guests.
- 0x457 6mo ago
  Aside from this probably being a scam or dead project, but they do say they either remove or disable batteries. Either way battery can be removed. > - Repairing old failed laptop components is more difficult than old servers. I think "run it until it's dead" kind of thing.
  - 6mo ago
ctippett 6mo ago
Collocating a bunch of lithium-ion heat pillows all in one place, what could go wrong!
- prmoustache 6mo ago
  Most laptops work perfectly fine with the battery removed and for those who cannot replacing it with a large capacitor is usually a solution.
  - subarctic 6mo ago
    Using a capacitor sounds interesting but also pretty tricky, have you done that yourself?
    - prmoustache 6mo ago
      I didn't as I never had a laptop with this issue but I have seen it done on a smartphone.
  - traderj0e 6mo ago
    I thought a lot of laptops don't work without the battery, especially the increasingly common unibody types.
calvinmorrison 6mo ago
uh yeah i mean we 'colo' at work because its cheaper than buying a windows server with multiple RDP licenses. We have some legacy stuff that must be run on site.... so we buy $200 laptops and people can remote in for years.
cactusplant7374 6mo ago
7 euro a month and unlimited bandwidth? Seems unlikely.
tracker1 6mo ago
Not sure if this is legit... I could see it working well enough if they require the laptop to support at least say thunderbolt3/usb4 then they can use a single connection interface to a management/dock interface that includes a network connection (1gb/2.5gb) The trouble is a lot of laptops won't power-on with the screen closed and have heavy sleep/suspend behaviors in general. Not to mention general airflow in whatever shelving system is used with the laptops, assuming 2-4 laptops per shelf, per 1u. Not to mention, one would probably want/need some means of ensuring appropriate driver support, or an appropriate Linux or other setup for said hardware. While I can see it working, depending on shipping costs can definitely see some problematic bits.

The folks that run the colo I keep our servers in would beat me to death with a shoe if I did either of these things: - Mount something in a rack not firmly attached to brackets or a shelf - Install anything with a battery larger than you'd find in a RAID card Not to mention all the other ways this is sub-par in terms of airflow, density, serviceability, out-of-band management, etc. I get the allure of it, but I wouldn't really want my gear anywhere near a bunch of laptops stuck in a cabinet.

perrygeo 6mo ago
Old laptops as low cost servers? Absolutely, build a homelab in your own basement, rent a cheap VPS, set up wireguard and viola - instant data center for tens of dollars per month. It's not production grade but you'll learn a ton. But colocation? Strip away the learning component and add production uptime requirements - why would you even consider using crusty old laptops for this? If you have production grade needs, look to a standard cloud provider or, at the very least, a colo facility where you can put production-grade equipment.
- GTP 6mo ago
  They aren't targeting big companies for sure, but maybe a small or medium-sized office could make use of this.
  - perrygeo 6mo ago
    I don't see it. Hobby projects can use a VPN tunnel to make a data center from local equipment. Real projects that choose colocation have uptime requirements that simply can't be met by random consumer hardware. The venn diagrams don't intersect. There's no middle ground where you try to run a real business on old laptops. That's insane. You either keep things small/hobby and stay simple, or graduate to production-grade equipment once you have real requirements. The middle ground, taking on production colocation problems plus the unreliability of random hardware, sounds like the worst of both worlds. There are both simpler and more robust options.
    - AussieWog93 6mo ago
      The problem with hosting locally is using residential internet. In Australia, for example, we're capping out at 100Mbit/s upload speeds on plans that cost ~US$70/mo and regularly go down for maintenance. In other countries with cheap symmetrical plans this may make more sense.
    - fabioz 6mo ago
      Initially I believe Google was known for getting unreliable hardware with good software to manage it (a single laptop probably won't cut it, but a bunch of laptops scattered around the globe could be interesting -- when you grow things fail all the time anyways).
Nyr 6mo ago
This is CLEARLY a scam. There is no way they are partnering with Hetzner, or charging just 7€/month flat rate... they specifically want to know the model of the laptop, and offer to send send a courrier to your door...
- IshKebab 6mo ago
  I would be really surprised if this was a scam. It doesn't have the smell of a scam at all. Who would target a very tech savvy audience just to get old laptops? Given that the "sign up" link goes to a survey form, my guess is this is just some idea someone had and they made this page to see if anyone actually wants it before they put any effort into making it happen.
  - Nyr 6mo ago
    Colo scams are pretty common. Some percentage of people will offer to send expensive laptops, and the scammers can discard the rest of "interested customers". It is inviable to colo old laptops, a regulatory nightmare - Hetzner would NEVER accept those in their datacenters. It is also absurd to think they are partnering with Hetzner to begin with. It makes no sense to believe they will even EXPORT laptops from Europe to the US if you choose the US location. It just makes no sense, so I don't get why I am getting downvoted.
    - IshKebab 6mo ago
      Just because it isn't a real product doesn't mean it is a scam. As I said, it is most likely just collecting interest for a potential business idea. You're being down-voted because it pretty clearly isn't a scam. It has none of the tell tail signs of a scam.

I’m curious if they remove the displays. Not every laptop works with the display closed and it might cause heat issues that throttle the CPU or reduce the life of the machine to run it like that long-term.
joecool1029 6mo ago
Just gonna point this out since I noticed it a few weeks ago and notice is still there, Hetzner has paused selling new colocation service: https://www.hetzner.com/colocation/ https://www.hetzner.com/colocation/ So this is probably a joke site or a scam.

I don't want to crap on peoples ideas. Really, I don't. But getting some closet case computer with unknown hardware and turning it into a server, at scale, is an impossible scheme. The only way to make it work would be to buy hundreds of laptops at once and refurb, new storage, and standardize with custom power delivery. Because who wants hundreds of laptop PSU's plugged into power strips. And those do in fact die. And then there's the horror of manually removing wifi hardware and batteries. Battery disposal is an issue. And having worked on hundreds of laptops, some of them are major pains in the neck to get to the battery. Consumer HP's come to mind. The bottom cover can be difficult to remove without breaking any of the clips. Point of Reference: 27 years in web hosting

that's how my university did a linux cluster for exercises
reincoder 6mo ago
I work for IPinfo and we operate a distributed network consisting of around 1,400 servers. I think we have reached a point where it is extremely hard for us purchase VPSes from interesting ASNs. To support lots of ISPs, universities, and different organizations we have been asking them if they have an old laptop lying around that they can host our software on. Goal is to reach 70,000 probes within the next couple of years. It is a simple probe software and we share some data or we can pay 20-30 bucks a month for it. We have a couple of NUCs in remote regions but no laptops yet. Basically, we are even happy if an ISP (or any one) hosts our software from a laptop dangling by a charging cable from a socket in some random corner. We can send over a RPI or NUC, but with remote hands, and setup and all that it can get quite expensive. So, we always first ask if they have an old laptop lying around and can install our software there. For us, at least, we are not interested in the hardware aspect. We are interested in the network. The old laptop approach only acts as a last resort. We will be more than happy to go with the predictability of a traditional VPS hosted in a traditional data center. Colocation, no matter what form it takes, involves a lot of moving parts.
- vrt_ 6mo ago
  Interesting challenge! My first thought: 70k probes is a lot and having to set that up is quite a task. Why not develop an phone app with exit node capabilities (similar to Tailscale) so you can use that for probing? The real win is that people move around, obtaining you even more data points from other network.
  - reincoder 6mo ago
    We actually have app-based data collection capabilities and initiatives. Our goal, or more appropriately, vision, is to map the internet in real time. This involves SSH access to devices to run different forms of measurements at a very high frequency and have control over those devices. Managing 70k probes is not going to be super hard. Managing 1,400 servers is just a normal business operation, not a technical challenge. Each probe has a standard OS-level configuration. Automation and configuration are deployed from a central system. Each probe is actively monitored and troubleshot. Data is dumped to a data warehouse. We make incremental improvements to our network. When servers go down, we talk to vendors. We do a lot of novel engineering things from the infrastructure, data, and research team. Having a very identical set of servers really allows us to focus on product and performance engineering, not troubleshooting engineering. With application-based probing, I assume it will complicate things quite a bit, as there are different operating systems, different devices, etc. For us, lately the challenge is not technical. It has been exclusively procurement. This quarter (https://ipinfo.io/blog/probenet-q1-2026-expansion https://ipinfo.io/blog/probenet-q1-2026-expansion), we exclusively focused on regional diversity which involved outreach to national ISPs or telecoms. Securing servers from telecoms is an extremely bureaucratic and expensive process. So, we are hoping to partner up with eyeball networks and the larger NOG community.
iJohnDoe 6mo ago
This is never a good idea. A ton of old batteries in one place. The batteries themselves are probably not a concern, but if something happens to the facility, then you have a ton of problems. Security of the facility is a concern if someone can get in and walk out with an armful of laptops. Laptops don’t scale from a stacking stand point. Sure, close the lids and line them up. Then you’ll have a lot of failures. Older laptops are intended to cool through the keyboard and top vents by the screen.

Yea this is a stupid idea. Old laptops don't have good performance per watt compared to new servers once you factor in that they are many many times slower.

Any recommendations on inexpensive colo for personal projects/servers? A few years ago ran across a few links for places to host a box and I didn't save them, and have regretted it. ISTR one was basically just industrial office space that was running a lower-tier colo, and another was some guys in a metro area that got a rack in a data center and were spreading the cost around with other like-minded folks. At my work I have machines in an Iron Mountain facility, but for personal projects I don't need anything like that, but I'd like something that's more capable than AWS that I'm paying $80/mo for a couple VMs.
- deadlyllama 6mo ago
  EC2 is pricey if it's all you're getting from AWS. If you have wierd requirements, colo may be a good option. Otherwise, just get a VPS or 3 and be done with it. You'll get a virtual KVM that lets you boot it off an ISO and set it up the way you want. Vultr, DigitalOcean, Linode, ... are long established VPS players. I'm cheap and buy VPSes off deals on lowendtalk.com. e.g. my backups are on a VPS with 3TB disk, 2GB RAM, 1 vCPU, USD7/mo. I suspect your USD80/mo budget would stretch to something amazing, by comparison.
  - linsomniac 6mo ago
    I'm familiar with Vultr, DO, Linode, none of them seem to have pricing that is compelling beyond EC2. OVH and Hetzner have some potentially compelling plans, but then I'm only saving a little bit. The call-out for colo is largely to save me from having to engineer a setup at my house for getting my Dell R720 with 256GB RAM online (switching to bridging, setting up a firewall/load balancer with backup, segmenting the networks). That does become easier if I decide I'm ok with 1gig rather than bumping it up to 10gig.
faangguyindia 6mo ago
I've been using Hetzner and OVH, i used to use GCP and AWS, my bills are now 1/10th of what they were if you do not use their platform specific features, it's better to run on bare metal with redundancy.
arjie 6mo ago
The core density is really low. You can run a 96 core Epyc from the previous generation at 700 W and that’s a lot of compute. It makes sense for a home server (and I have an old Mac playing that role at home) but otherwise I don’t think it makes sense unless you’re taking off the display and racking them super tight. Even then, you’re probably better off with Cloudflare tunnel and using it as a home server.
petterroea 6mo ago
Old laptops are also notorious[1] for being fire bombs with bad batteries. If I was a hetzner customer I'd be pissed if my server burned because someone's 2 minute battery life 10 year old school pc was hosted in the neighbouring rack. Doesn't seem like a great business idea. [1]: anecdotally, seems everyone has a laptop lying around with a cursed battery
- subarctic 6mo ago
  That's what I was thinking too, don't data centers have policies about this stuff? I wonder who'd be liable if your laptop burst into flames
znnajdla 6mo ago
I do this at my homelab and it’s a really fun thing to do. Collect old laptops and install Linux or Tart for macOS and suddenly you have a fleet of computing power equivalent to paying thousands to AWS. Building reliability and failover is actually a fun engineering problem, use CockroachDB and RustFS. Adding capacity is just about scouting for second hand ewaste.

wouterjanl 6mo ago
Funny, I had a similar idea this morning in the shower. I was thinking about how distributed digital infrastructure could be achieved in practice. Running some music streaming and photo server on an old laptop at home that I access via tailscale has proved surprisingly smooth. I feel there is some future in empowering users by giving them access to a cloud on hardware that is actually owned by the user. It would be a way to achieve absolute digital freedom, no lock-in and if done in a secure way privacy friendly. Hell it's the OG idea of the internet! The question is how to bring this to non-technical users. I know many people who are getting sick of paying each month both to Apple and Google for storing their ever growing pile of pictures. This solution of course does imply some sort of lock-in as your tied to a subscription and it's probably quite the hassle to get your laptop back. Also the fire hazard seems like a legit concern.

They remove the battery! That was my first question. I have an old Lenovo laptop that works fine with the battery completely removed--but I have to disconnect the power and reconnect it before the soft power-on switch will work. I wonder how they handle powering on finicky laptops with those "soft" power buttons.

This looks really cool. I have never colo'd my laptop, but I do work off my Windows laptop from my Mac via Parsec (remote viewing software for gaming) and by flipping system settings so my Windows machine never turns off when connected to the power bank and lid is closed. There are obviously hiccups (if internet goes out, if Windows decides to restart from an update, etc.), but it mostly just works and I think I've only had 2 instances in the past 3 months where it's gone offline. I use Tailscale on top to provide a universal mouse server for my 3d mouse, and I'm able to magically CAD from my Mac. Highly recommend if you need to use one OS/machine for some specific software (especially if it's beefy/heavy) but prefer using another as your daily driver.

What's the difference between this and 1. setting my laptop at home and 2. connect it through Tailscale? I lose ownership of my laptop, you install whatever software you want on it (with the security risks that it conveys) and in turn "you let me connect to my computer"?
- jve 6mo ago
  Well connectivity (speed) and energy stability may be 2 of them (your internet may go down along with electricity). Or look at it another way: you wanted to buy/rent a server you intended to put in datacenter anyway. Now you can do the same with laptop.

    Jokes on you I got a 20kWh backup UPS on the entire house. Now on a serious note: internet can go down anywhere, even for them. There is nowhere stated that, if your old hardware misbehaves, you can use others, and there are privacy concerns with running your stuff on their software stack… So I don’t see a huge advantage honestly.

€7/month is mad considering the hardware is my own.
- yonatan8070 6mo ago
  Is it? It doesn't sound outragous to me, given that they provide you with however much power you need, ans also networking and people to maintain the facility. I asked ChatGPT to estimate how much darwing 15W continuously in Amsterdam would cost you per month, and it came up with a range of 2.58€-3.41€ per month. So that's potentially more than half of their fee. If your laptop is particularly power efficient, you'd also be subsidizing higher-powered laptops. As far as I see there's nothing preventing you from sending a 400W gaming laptop and mining crypto or running an LLM agent 24/7.
- michaelt 6mo ago
  €7/month is both too much and too little. The cheapest USB KVM-over-IP costs about €50 - that's 8 months of colo fees gone. Colo 'remote hands' in western countries can cost €120/hour, once all expenses and overheads are taken into account. Admittedly, that's for someone to drop what they're doing and rush to your sever. But getting that laptop unpacked, checked over, labelled, installed in a rack, associated to a customer account, powered up and working is going to cost 3 months of fees at least. One laptop gets lost or damaged during shipping, or shows up mysteriously broken when the customer claims it worked when they sent it? That's a €200 device gone, 28 months of colo fees. You can argue your way out of it, but the guy doing the arguing is the €120/hour remote hands guy. It'd be easy to lose money on this.
  - qmr 6mo ago
    There's no way they're offering 24/7 KVM for this. Cheap colos you need to write / call to get an on demand KVM then wait some hours or days for a tech to plug it in. The operator is in no way responsible for shipping damage, not sure why you imply they would be.
radu_floricica 6mo ago
The advantage of a laptop is exactly that you can easily host it at home, and own everything. I have one - with an UPS also holding the router and fiber optic and an external HDD. I'm actually working right now to version 2.0 which is a beefed up version - still used laptop (found a great deal on a lenovo P1), but slightly more expensive and I'm waiting on some parts to upgrade. Should be able to even hold the production environment in a pinch. Ah, and obviously you put a claude/codex on it, so your actual work is just ... installing claude, and maybe a linux. The rest is done by the AI - setup, scripting etc. As a colocated option... I see it work for some people. But it'd be a niche offering, when the whole value proposition is "make my own, with blackjack and hookers".

  Do you not get memory errors without ECC RAM?
  - adrian_b 6mo ago
    There are laptops with ECC RAM, but they are uncommon. Otherwise, the effect of memory errors depends on the use case. If the laptop or mini-PC is used as a router/firewall/Internet gateway, then memory errors are usually not important, because they would result in corrupted network packets that are likely to be detected at the endpoints of a network connection. If the laptop or mini-PC is used as an e-mail server or a Web server, then a fraction of the memory errors may result in a stored file that becomes corrupted. At the small amounts of memory typical for a laptop or mini-PC, unless the PC is many years old there should be no more than a few memory errors per year at most, and the majority of the errors might not result in file corruption, but sometimes they may cause weird behavior requiring a computer reboot. Anecdotally, during the years I have seen on the Internet a non-negligible amount of big files, e.g. movies, which appear to have bit flips that are likely to have been caused by their hosting on servers without ECC memory. Fortunately, in movies a small number of bit flips will not cause severe quality degradation. With more valuable data, one must use ECC memory to avoid such problems.

Suppose we set aside the concerns in this thread about the legitimacy of this. How would this work when the old hardware inevitably needs to be serviced (mechanical hard drive failure, memory errors, dust buildup, etc)? Would they have technicians on-site available to service whatever random laptop you send them? If your laptop dies do they ship it back to you so you can fix it and send it back? Or what if you bork the OS by accident? Will their KVM solution allow you to upload an ISO and plug it in over some USB drive emulation?

Ran an old laptop as home server for years. It’s OKish as a starting point into selfhosted world but overall not ideal.

What’s the point if I can just connect it to my router and not pay any money to anyone, expect some electricity price, which would be like ten times cheaper.

OK then. I’d have another laptop at some else place then, and have two powerful servers for like still one fifth of the price. Can you beat that?

Maybe I'm in the minority... but this seems like an extremely compelling offering for certain use-cases. Not for enterprises, but for individuals and small businesses. My off-site backup is a thinkpad x230 with a 1 TB HDD. It's currently at my friends house, and I access it with tailscale. 7 eur/month to colocate this in a datacenter with stable (and fast) Internet + power seems like a pretty good deal. I can understand some of the concerns with user-provided hardware. Maybe a better model, would be for CoLaptop to offer hardware themselves. This would allow them to standardize on a few models, which opens up many possible improvements such as central DC power, power efficient BIOS settings, enclosures with cooling ducts, etc. They can still follow the "old laptop as a server" model by buying off-lease laptops from the corporate world.
- torginus 6mo ago
  I mean we literally did this in one of my previous places. We took all the old laptops that were to be junked by IT, and used them as a selenium test farm. We saved like $100k per month on the AWS bill at the cost of basically electricity. If all the machines were running Windows, the difference would've been even more drastic. What I dont get is that we have these autoscaling technologies that allow software to be fault tolerant to hardware failure, yet companies still insist on buying expensive server grade HW for everything.
  - iso1631 6mo ago
    Been through this recently in a fairly large enterprise We have some in house software which runs in k8s. Total throughput peaks at about 1mbit a second of control traffic - it's controlling some other devices which are on dedicated hardware. Total of 24GB of ram. The software team say it needs to run across 3 different servers for resilience purposes. The VM team want to use neutronix as their VM platform, so they can live migrate one VM to another. They insist on 25gbit networking, and for resilience purposes that needs to be mlagged The network team also have to have multiple switches and routers, again for resilience. So rather than having 3 $1000 laptops running bare metal kubes hanging off a pair of $500 1G switches eating maybe 200W, we have a $140k BOM sucking up 2kW. When something goes wrong all those layers of resilience will no doubt fight each other. The hardware drops, so the VM freezes as it restored onto another host, so K8s moves the workloads, then the VM comes back, the k8s gets confused (maybe? I don't know how k8s works). It's all needlessly overspecced costing 30 times as much as it should. But from each individual team it makes sense. They don't want to be blamed if it doesn't work, they don't have to find the money. It's different departments.

I had this idea for dirt-cheap colo where it's just a warehouse that has warehouse racks for putting whatever you want on the rack. Rates based on linear feet, bandwidth, and power consumption. Power would be delivered with a 15-minute uptime guarantee, meaning you have at least 15 minutes to gracefully shut down in the event of loss of power. Advantage is reasonably secure location and quality Internet connection. Target market is nerds who don't want all that crap in their closets.

Hey, this is great. Many of my old laptops become my "servers", so I'd definitely pay for this. One question I have, in case someone from CoLaptop is reading: So, one time I had this White "Chiclet" MacBook and I had it powered on all the time, I didn't know at the time but that destroyed the battery and when I unplugged it/plugged it again (because I moved it to a different place after like 4 years) it just didn't power up, fortunately I was able to extract the HDD and its contents. Now I have one old MacBook Air and one old MacBook Pro as "servers", and I regularly disconnect them from power (but keep them on), I do this for like a day every 3-4 weeks, and haven't had that issue, battery health is still good etc... So, what do you recommend for this? Or is this something you'll do as part of the CoLo service?

A friend of mine sent it to me and it seems like an interesting option now that hardware pricing has gone insane?

Eeek, I can't imagine what this is like if it scales. What happens to the fire risk when theres 20,000 laptops with aging batteries all sitting together? I hope they take the batteries out, however many laptops use batteries to smooth out power fluctuations. Laptops aren't designed to be servers - peg your laptop CPU and GPU at 100% and see how long it lasts, I've done this before and the answer is about "2 months", yep sure, this effort isn't targeting that workload, but how many bad apples does it take to start a fire? In their page they say "kubernetes server - no problem" kubernetes DOES keep the CPUs busy, not pegged, but busy enough so that they wont step down their frequency. I admire the effort to reuse old tech, but boy oh boy would I not want to be a sysadmin here!

cucumber3732842 6mo ago
I worked for a place that did something akin to this in the early 2010s. Someone figured out how to add 32-bit company laptops to the virtualization cluster (likely because they were using one as a stand in for a server that at the time would have been in the works but not yet purchased) and so once that work had been incurred they just kept "retiring" unserviceable company laptops to the cluster. Imagine a standard wire metro-rack crammed in a telecom closet beside a normal server rack. Now imagine that metro rack literally full of Toshiba Satellite Pro's from about 2005-9. The cluster hosted virtual machines for testing. No fires, no hardware problems. No special cooling other than the mini-split that was in the closet to cool the server rack. They just kept trucking. But modern hardware is much more high strung and I don't doubt you'd have weird failures. Edit: Back then VMs were how things were done and RAM was seemingly always the bottleneck by a mile, so the cluster did add up to a meaningful amount of extra performance compared to not having it.

All the big 3 cloud providers suck if you use them purely as VPS.

Paying $90/yr for a 4 vCPU¹ / 16 GB / 320 GB SSD, had some downtime exactly once in two years (they’ve had to switch their IPv4 space in Tokyo). Affiliate link: https://ale.sh/r/ssdnodes https://ale.sh/r/ssdnodes [1]: Intel Xeon E5-2650 v4 (4) @ 2.199GHz – not great, I know, but to reiterate: that’s for $90 a year.

Sure my old laptop does have more RAM and a bigger SSD, but I bet it's also less reliable than Hetzner's servers, and is likely to suddenly die some day. So is the tradeoff really worth it? It's hard for me to believe that this is a genuine improvement for most things. The only definite winning case I can think of is if I have a process I want to run, but I don't care if it just suddenly stops working.

However, I have solid backup setup in place (ZFS send and recv to other physical hosts in different physical locations) with that in mind, so I haven’t lost data with Hetzner.

burnt-resistor 6mo ago

Hmm, there's might something to this: + The usual limiting factor in data centers is power, so laptops could be more optimized for greater cycle efficiency per power than comparable old servers. + Laptops are generally compact and so achieve greater rack densities than individual co-lo servers. I'm thinking about 34 or 51 laptops could be stored in 9 or 10U either 2 or 3 rows deep by 17 wide. + Shipping a laptop to a co-lo data center is cheaper than a 1U server. ~ Reusing electronics saves e-waste and reduces unnecessary consumption, either old servers or old laptops. - Laptops lack ECC RAM. - Laptops typically don't use nearly as fast CPUs or RAM as contemporaneous servers. - Laptops are limited in their storage options. - Laptops lack remote, lights-out management of real servers. - Repairing old failed laptop components is more difficult than old servers. ~ Old laptops tend not to have usable batteries, so there's unlikely to be much an inherently distributed battery backup capability. - Old laptop batteries of various origins could be a li-ion NMC fire hazard at scale. ~ Reusing old stuff at any sort of scale would prefer standardization, and it's sometimes difficult to amass many of the same discontinued model.

I think it's one of those ideas that only works with nostalgia or hoarding impulses to support it. I think normal virtualization approaches are far more power efficient, at a fleet level, than any kind of cluster of laptop scenarios. You can pile in the cores and amortize the costs of memory controllers etc. over a large set of guests. It is a funny way to get features of both worlds. One reason to want colo (rather than VMs) is for predictability, but laptops still give you the funny throughput problems, because of thermal throttling instead of competing guests.

Aside from this probably being a scam or dead project, but they do say they either remove or disable batteries. Either way battery can be removed. > - Repairing old failed laptop components is more difficult than old servers. I think "run it until it's dead" kind of thing.

Most laptops work perfectly fine with the battery removed and for those who cannot replacing it with a large capacitor is usually a solution.

tracker1 6mo ago

Not sure if this is legit... I could see it working well enough if they require the laptop to support at least say thunderbolt3/usb4 then they can use a single connection interface to a management/dock interface that includes a network connection (1gb/2.5gb) The trouble is a lot of laptops won't power-on with the screen closed and have heavy sleep/suspend behaviors in general. Not to mention general airflow in whatever shelving system is used with the laptops, assuming 2-4 laptops per shelf, per 1u. Not to mention, one would probably want/need some means of ensuring appropriate driver support, or an appropriate Linux or other setup for said hardware. While I can see it working, depending on shipping costs can definitely see some problematic bits.

The folks that run the colo I keep our servers in would beat me to death with a shoe if I did either of these things: - Mount something in a rack not firmly attached to brackets or a shelf - Install anything with a battery larger than you'd find in a RAID card Not to mention all the other ways this is sub-par in terms of airflow, density, serviceability, out-of-band management, etc. I get the allure of it, but I wouldn't really want my gear anywhere near a bunch of laptops stuck in a cabinet.

perrygeo 6mo ago

Old laptops as low cost servers? Absolutely, build a homelab in your own basement, rent a cheap VPS, set up wireguard and viola - instant data center for tens of dollars per month. It's not production grade but you'll learn a ton. But colocation? Strip away the learning component and add production uptime requirements - why would you even consider using crusty old laptops for this? If you have production grade needs, look to a standard cloud provider or, at the very least, a colo facility where you can put production-grade equipment.

GTP 6mo ago
They aren't targeting big companies for sure, but maybe a small or medium-sized office could make use of this.
- perrygeo 6mo ago
  I don't see it. Hobby projects can use a VPN tunnel to make a data center from local equipment. Real projects that choose colocation have uptime requirements that simply can't be met by random consumer hardware. The venn diagrams don't intersect. There's no middle ground where you try to run a real business on old laptops. That's insane. You either keep things small/hobby and stay simple, or graduate to production-grade equipment once you have real requirements. The middle ground, taking on production colocation problems plus the unreliability of random hardware, sounds like the worst of both worlds. There are both simpler and more robust options.
  - AussieWog93 6mo ago
    The problem with hosting locally is using residential internet. In Australia, for example, we're capping out at 100Mbit/s upload speeds on plans that cost ~US$70/mo and regularly go down for maintenance. In other countries with cheap symmetrical plans this may make more sense.
  - fabioz 6mo ago

This is CLEARLY a scam. There is no way they are partnering with Hetzner, or charging just 7€/month flat rate... they specifically want to know the model of the laptop, and offer to send send a courrier to your door...

IshKebab 6mo ago
I would be really surprised if this was a scam. It doesn't have the smell of a scam at all. Who would target a very tech savvy audience just to get old laptops? Given that the "sign up" link goes to a survey form, my guess is this is just some idea someone had and they made this page to see if anyone actually wants it before they put any effort into making it happen.
- Nyr 6mo ago
  Colo scams are pretty common. Some percentage of people will offer to send expensive laptops, and the scammers can discard the rest of "interested customers". It is inviable to colo old laptops, a regulatory nightmare - Hetzner would NEVER accept those in their datacenters. It is also absurd to think they are partnering with Hetzner to begin with. It makes no sense to believe they will even EXPORT laptops from Europe to the US if you choose the US location. It just makes no sense, so I don't get why I am getting downvoted.
  - IshKebab 6mo ago
    Just because it isn't a real product doesn't mean it is a scam. As I said, it is most likely just collecting interest for a potential business idea. You're being down-voted because it pretty clearly isn't a scam. It has none of the tell tail signs of a scam.

I don't want to crap on peoples ideas. Really, I don't. But getting some closet case computer with unknown hardware and turning it into a server, at scale, is an impossible scheme. The only way to make it work would be to buy hundreds of laptops at once and refurb, new storage, and standardize with custom power delivery. Because who wants hundreds of laptop PSU's plugged into power strips. And those do in fact die. And then there's the horror of manually removing wifi hardware and batteries. Battery disposal is an issue. And having worked on hundreds of laptops, some of them are major pains in the neck to get to the battery. Consumer HP's come to mind. The bottom cover can be difficult to remove without breaking any of the clips. Point of Reference: 27 years in web hosting

that's how my university did a linux cluster for exercises

reincoder 6mo ago

I work for IPinfo and we operate a distributed network consisting of around 1,400 servers. I think we have reached a point where it is extremely hard for us purchase VPSes from interesting ASNs. To support lots of ISPs, universities, and different organizations we have been asking them if they have an old laptop lying around that they can host our software on. Goal is to reach 70,000 probes within the next couple of years. It is a simple probe software and we share some data or we can pay 20-30 bucks a month for it. We have a couple of NUCs in remote regions but no laptops yet. Basically, we are even happy if an ISP (or any one) hosts our software from a laptop dangling by a charging cable from a socket in some random corner. We can send over a RPI or NUC, but with remote hands, and setup and all that it can get quite expensive. So, we always first ask if they have an old laptop lying around and can install our software there. For us, at least, we are not interested in the hardware aspect. We are interested in the network. The old laptop approach only acts as a last resort. We will be more than happy to go with the predictability of a traditional VPS hosted in a traditional data center. Colocation, no matter what form it takes, involves a lot of moving parts.

vrt_ 6mo ago
Interesting challenge! My first thought: 70k probes is a lot and having to set that up is quite a task. Why not develop an phone app with exit node capabilities (similar to Tailscale) so you can use that for probing? The real win is that people move around, obtaining you even more data points from other network.
- reincoder 6mo ago
  We actually have app-based data collection capabilities and initiatives. Our goal, or more appropriately, vision, is to map the internet in real time. This involves SSH access to devices to run different forms of measurements at a very high frequency and have control over those devices. Managing 70k probes is not going to be super hard. Managing 1,400 servers is just a normal business operation, not a technical challenge. Each probe has a standard OS-level configuration. Automation and configuration are deployed from a central system. Each probe is actively monitored and troubleshot. Data is dumped to a data warehouse. We make incremental improvements to our network. When servers go down, we talk to vendors. We do a lot of novel engineering things from the infrastructure, data, and research team. Having a very identical set of servers really allows us to focus on product and performance engineering, not troubleshooting engineering. With application-based probing, I assume it will complicate things quite a bit, as there are different operating systems, different devices, etc. For us, lately the challenge is not technical. It has been exclusively procurement. This quarter (https://ipinfo.io/blog/probenet-q1-2026-expansion https://ipinfo.io/blog/probenet-q1-2026-expansion), we exclusively focused on regional diversity which involved outreach to national ISPs or telecoms. Securing servers from telecoms is an extremely bureaucratic and expensive process. So, we are hoping to partner up with eyeball networks and the larger NOG community.

iJohnDoe 6mo ago

This is never a good idea. A ton of old batteries in one place. The batteries themselves are probably not a concern, but if something happens to the facility, then you have a ton of problems. Security of the facility is a concern if someone can get in and walk out with an armful of laptops. Laptops don’t scale from a stacking stand point. Sure, close the lids and line them up. Then you’ll have a lot of failures. Older laptops are intended to cool through the keyboard and top vents by the screen.

Any recommendations on inexpensive colo for personal projects/servers? A few years ago ran across a few links for places to host a box and I didn't save them, and have regretted it. ISTR one was basically just industrial office space that was running a lower-tier colo, and another was some guys in a metro area that got a rack in a data center and were spreading the cost around with other like-minded folks. At my work I have machines in an Iron Mountain facility, but for personal projects I don't need anything like that, but I'd like something that's more capable than AWS that I'm paying $80/mo for a couple VMs.

deadlyllama 6mo ago
EC2 is pricey if it's all you're getting from AWS. If you have wierd requirements, colo may be a good option. Otherwise, just get a VPS or 3 and be done with it. You'll get a virtual KVM that lets you boot it off an ISO and set it up the way you want. Vultr, DigitalOcean, Linode, ... are long established VPS players. I'm cheap and buy VPSes off deals on lowendtalk.com. e.g. my backups are on a VPS with 3TB disk, 2GB RAM, 1 vCPU, USD7/mo. I suspect your USD80/mo budget would stretch to something amazing, by comparison.
- linsomniac 6mo ago
  I'm familiar with Vultr, DO, Linode, none of them seem to have pricing that is compelling beyond EC2. OVH and Hetzner have some potentially compelling plans, but then I'm only saving a little bit. The call-out for colo is largely to save me from having to engineer a setup at my house for getting my Dell R720 with 256GB RAM online (switching to bridging, setting up a firewall/load balancer with backup, segmenting the networks). That does become easier if I decide I'm ok with 1gig rather than bumping it up to 10gig.

arjie 6mo ago

The core density is really low. You can run a 96 core Epyc from the previous generation at 700 W and that’s a lot of compute. It makes sense for a home server (and I have an old Mac playing that role at home) but otherwise I don’t think it makes sense unless you’re taking off the display and racking them super tight. Even then, you’re probably better off with Cloudflare tunnel and using it as a home server.

wouterjanl 6mo ago

Funny, I had a similar idea this morning in the shower. I was thinking about how distributed digital infrastructure could be achieved in practice. Running some music streaming and photo server on an old laptop at home that I access via tailscale has proved surprisingly smooth. I feel there is some future in empowering users by giving them access to a cloud on hardware that is actually owned by the user. It would be a way to achieve absolute digital freedom, no lock-in and if done in a secure way privacy friendly. Hell it's the OG idea of the internet! The question is how to bring this to non-technical users. I know many people who are getting sick of paying each month both to Apple and Google for storing their ever growing pile of pictures. This solution of course does imply some sort of lock-in as your tied to a subscription and it's probably quite the hassle to get your laptop back. Also the fire hazard seems like a legit concern. I nevertheless do hear some music here.

This looks really cool. I have never colo'd my laptop, but I do work off my Windows laptop from my Mac via Parsec (remote viewing software for gaming) and by flipping system settings so my Windows machine never turns off when connected to the power bank and lid is closed. There are obviously hiccups (if internet goes out, if Windows decides to restart from an update, etc.), but it mostly just works and I think I've only had 2 instances in the past 3 months where it's gone offline. I use Tailscale on top to provide a universal mouse server for my 3d mouse, and I'm able to magically CAD from my Mac. Highly recommend if you need to use one OS/machine for some specific software (especially if it's beefy/heavy) but prefer using another as your daily driver.

jve 6mo ago
Well connectivity (speed) and energy stability may be 2 of them (your internet may go down along with electricity). Or look at it another way: you wanted to buy/rent a server you intended to put in datacenter anyway. Now you can do the same with laptop.

  Jokes on you I got a 20kWh backup UPS on the entire house. Now on a serious note: internet can go down anywhere, even for them.

€7/month is mad considering the hardware is my own.

yonatan8070 6mo ago
Is it? It doesn't sound outragous to me, given that they provide you with however much power you need, ans also networking and people to maintain the facility. I asked ChatGPT to estimate how much darwing 15W continuously in Amsterdam would cost you per month, and it came up with a range of 2.58€-3.41€ per month. So that's potentially more than half of their fee. If your laptop is particularly power efficient, you'd also be subsidizing higher-powered laptops. As far as I see there's nothing preventing you from sending a 400W gaming laptop and mining crypto or running an LLM agent 24/7.
michaelt 6mo ago
€7/month is both too much and too little. The cheapest USB KVM-over-IP costs about €50 - that's 8 months of colo fees gone. Colo 'remote hands' in western countries can cost €120/hour, once all expenses and overheads are taken into account. Admittedly, that's for someone to drop what they're doing and rush to your sever. But getting that laptop unpacked, checked over, labelled, installed in a rack, associated to a customer account, powered up and working is going to cost 3 months of fees at least. One laptop gets lost or damaged during shipping, or shows up mysteriously broken when the customer claims it worked when they sent it? That's a €200 device gone, 28 months of colo fees. You can argue your way out of it, but the guy doing the arguing is the €120/hour remote hands guy. It'd be easy to lose money on this.
- qmr 6mo ago
  There's no way they're offering 24/7 KVM for this. Cheap colos you need to write / call to get an on demand KVM then wait some hours or days for a tech to plug it in. The operator is in no way responsible for shipping damage, not sure why you imply they would be.

radu_floricica 6mo ago

The advantage of a laptop is exactly that you can easily host it at home, and own everything. I have one - with an UPS also holding the router and fiber optic and an external HDD. I'm actually working right now to version 2.0 which is a beefed up version - still used laptop (found a great deal on a lenovo P1), but slightly more expensive and I'm waiting on some parts to upgrade. Should be able to even hold the production environment in a pinch. Ah, and obviously you put a claude/codex on it, so your actual work is just ... installing claude, and maybe a linux. The rest is done by the AI - setup, scripting etc. As a colocated option... I see it work for some people. But it'd be a niche offering, when the whole value proposition is "make my own, with blackjack and hookers".

Do you not get memory errors without ECC RAM?
- adrian_b 6mo ago
  There are laptops with ECC RAM, but they are uncommon. Otherwise, the effect of memory errors depends on the use case. If the laptop or mini-PC is used as a router/firewall/Internet gateway, then memory errors are usually not important, because they would result in corrupted network packets that are likely to be detected at the endpoints of a network connection. If the laptop or mini-PC is used as an e-mail server or a Web server, then a fraction of the memory errors may result in a stored file that becomes corrupted. At the small amounts of memory typical for a laptop or mini-PC, unless the PC is many years old there should be no more than a few memory errors per year at most, and the majority of the errors might not result in file corruption, but sometimes they may cause weird behavior requiring a computer reboot. Anecdotally, during the years I have seen on the Internet a non-negligible amount of big files, e.g. movies, which appear to have bit flips that are likely to have been caused by their hosting on servers without ECC memory. Fortunately, in movies a small number of bit flips will not cause severe quality degradation. With more valuable data, one must use ECC memory to avoid such problems.

Suppose we set aside the concerns in this thread about the legitimacy of this. How would this work when the old hardware inevitably needs to be serviced (mechanical hard drive failure, memory errors, dust buildup, etc)? Would they have technicians on-site available to service whatever random laptop you send them? If your laptop dies do they ship it back to you so you can fix it and send it back? Or what if you bork the OS by accident? Will their KVM solution allow you to upload an ISO and plug it in over some USB drive emulation?

Maybe I'm in the minority... but this seems like an extremely compelling offering for certain use-cases. Not for enterprises, but for individuals and small businesses. My off-site backup is a thinkpad x230 with a 1 TB HDD. It's currently at my friends house, and I access it with tailscale. 7 eur/month to colocate this in a datacenter with stable (and fast) Internet + power seems like a pretty good deal. I can understand some of the concerns with user-provided hardware. Maybe a better model, would be for CoLaptop to offer hardware themselves. This would allow them to standardize on a few models, which opens up many possible improvements such as central DC power, power efficient BIOS settings, enclosures with cooling ducts, etc. They can still follow the "old laptop as a server" model by buying off-lease laptops from the corporate world.

torginus 6mo ago
I mean we literally did this in one of my previous places. We took all the old laptops that were to be junked by IT, and used them as a selenium test farm.

What I dont get is that we have these autoscaling technologies that allow software to be fault tolerant to hardware failure, yet companies still insist on buying expensive server grade HW for everything.
- iso1631 6mo ago
  Been through this recently in a fairly large enterprise We have some in house software which runs in k8s. Total throughput peaks at about 1mbit a second of control traffic - it's controlling some other devices which are on dedicated hardware. Total of 24GB of ram. The software team say it needs to run across 3 different servers for resilience purposes. The VM team want to use neutronix as their VM platform, so they can live migrate one VM to another. They insist on 25gbit networking, and for resilience purposes that needs to be mlagged The network team also have to have multiple switches and routers, again for resilience. So rather than having 3 $1000 laptops running bare metal kubes hanging off a pair of $500 1G switches eating maybe 200W, we have a $140k BOM sucking up 2kW. When something goes wrong all those layers of resilience will no doubt fight each other. The hardware drops, so the VM freezes as it restored onto another host, so K8s moves the workloads, then the VM comes back, the k8s gets confused (maybe? I don't know how k8s works). It's all needlessly overspecced costing 30 times as much as it should. But from each individual team it makes sense. They don't want to be blamed if it doesn't work, they don't have to find the money. It's different departments.

Very strongly reminds me of Mac Mini Colo - https://www.macminivault.com/mac-mini-colocation/ https://www.macminivault.com/mac-mini-colocation/ - it's a clever idea.

Finding laptops that can support multiple hard drives is becoming more challenging every year. The 15"-17" workstation class Dell Precision, Lenovo P*, HP Zbook, and Framework 16 laptops are well suited to this purpose. Some of them even came with Xeon CPUs and ECC RAM support.

Let’s start a company that does this with old phones. If they’re recent waterproof models you could invert them in cold water and rack them pretty densely while managing heat easily. An ice water Beowulf cluster of iPhone 15s would be a lot of compute in one Yeti cooler.

i don't think phones are THAT watertight... they're not tested for long term submersion. usualy they don't even guarantee waterproof rating for more than first two years or when there are signs of wear. should work with some non-conductive oil or fluorintert tho...

I think i like the idea. But why specifically laptops, why won't they accept small computers like thinkcentres for example ?

Why not old android phones? :-D

I've wanted to do that with an old laptop and send it to be hosted at a friend's house. The advantage I found with a laptop : 1. Only two cables, power and ethernet. Installation and removal is quick. 2. Comes bundled with keyboard and screen so no need for monitor 3. Usually very low power consumption and low heat. 4. Light, it can be stored anywhere. So to answer your question, I'm guessing all of the above?

Have an old Mac book pro sitting in my office as a self hosted Mac GitHub runner and it works great. My biggest complaint used to be that it would occasionally restart after a system update and I’d have to unlock FileVault in person, but macOS 26 now allows unlocks over ssh.

I had this idea for dirt-cheap colo where it's just a warehouse that has warehouse racks for putting whatever you want on the rack. Rates based on linear feet, bandwidth, and power consumption. Power would be delivered with a 15-minute uptime guarantee, meaning you have at least 15 minutes to gracefully shut down in the event of loss of power. Advantage is reasonably secure location and quality Internet connection. Target market is nerds who don't want all that crap in their closets.

Hey, this is great. Many of my old laptops become my "servers", so I'd definitely pay for this. One question I have, in case someone from CoLaptop is reading: So, one time I had this White "Chiclet" MacBook and I had it powered on all the time, I didn't know at the time but that destroyed the battery and when I unplugged it/plugged it again (because I moved it to a different place after like 4 years) it just didn't power up, fortunately I was able to extract the HDD and its contents. Now I have one old MacBook Air and one old MacBook Pro as "servers", and I regularly disconnect them from power (but keep them on), I do this for like a day every 3-4 weeks, and haven't had that issue, battery health is still good etc... So, what do you recommend for this? Or is this something you'll do as part of the CoLo service?

If I am going to pay a colo I am going to get a proper server. Or run the laptop at home and tunnel Also sounds like a recipe for fire.

It's an interesting idea, and it might even work for some people who have overpowered gaming laptops that can't run Windows 11 (thanks, Microsoft!). But man, people have no idea how powerful just a few cores of a modern AMD EPYC are. Try a Linode instance with a few dedicated cores and see if that's competitive with shipping your old alienware to a colo.

This idea kinda makes sense if it's an old Mac mini, since you can't get Mac servers normally. MacBook would be sus due to the battery.

Will they let me send my laptop if I'm a North Korean remote worker?

Boss: This is not working! Dev: Works on my machine... Boss: Fine, let us deploy your laptop.

Overall good idea but why is had to be a laptop? A mini computer will be much better for this
