Are RasPi's actually performant for this kind of use case? Like relative to just getting a random desktop or server rack... thingy? I can't help but feel like at one point you're just generating a bunch of garbage/wasting energy compared to more performant offerings that might be more efficient all around. Is it price? (Just to be clear, I think "having fun" is a fine excuse to do most stuff, but they're talking about "replacing usage of AWS" which sounds a hell of a lot like a serious business thingy)

Hardly performant enough. You are way better working with a Xeon server, even used ones.

  Would certainly be interesting to see the comparison in terms of computing power and power usage between a small pi cluster and a single XEON server. I imagine such a thing would draw at least 200W? And pi's maybe 5 watts? So in theory, 30 - 40 pis vs a single server? The pis also have an advantage in terms of redundancy. A single pi going down shouldn't be a problem and very easily replaceable. Would be a really interesting article.

    VS desktop class hardware, the power draw is a giant plus also leading to no or quiet fans. An old laptop, however, has about the same power/performance consumption while including an USP, keyboard, mouse and screen, albeit it is bigger and has no GPIO if you need those. That being said, I am running a NAS and PiHole on a RPi4B right now and am happy. I am planning on turning an old laptop with busted hinges into a server with a nice housing though. I'm very interested how it's going to pan out :) Edit: I had a 1U server with 2x intel CPUs (16 threads all in all I think?) with 32G RAM in 2012 or so and it didn't see much use. It was LOUD (small screaming fans that pushed air through the chasis) so it didn't see much use.

      Indeed, if I'm going to build a home or small-office server, I want a 4U case, just so I can use fans that are large enough to be reasonably quiet (let's say, 80mm or bigger). Bonus points if it could somehow run 120 or 140 mm fans, but I haven't seen such a beast. I've seen 1U servers in action at a client, and they're horrifyingly loud.

        If you don't really need a rack case, I'd even go as far as to use a normal case with regular Noctua fans. The hardware for PCs is probably more expensive though (plus no ECC, single socket, ...).

    I'll be addressing that in a video later today: https://www.youtube.com/watch?v=8zXG4ySy1m8 https://www.youtube.com/watch?v=8zXG4ySy1m8 There are situations where the economics slightly favor the Pi, but they're fairly narrow with the current gen.

  Used Xeons are cheap and plentiful on eBay and Craigslist. The power consumption and jet engine fans are something most people wouldn’t tolerate. That’s why I use PIs and custom built a NAS with a supermicro mobo and an i3 (ECC compatible). The rig the author has is bordering on the ridiculous side and can never match a Xeon, or Xeon cluster.
