> E5-2650v2 Those are pretty awful by current standards - you could buy a midrange minipc or laptop from a few cpu generations ago and get similar/better compute performance for much lower power draw. If you're just running a homelab and you don't have poor quality wall power or something you aren't really gaining anything from ECC ram either. Although you said you were thinking of upgrading, so you're probably aware of this already.

>If you're just running a homelab and you don't have poor quality wall power or something you aren't really gaining anything from ECC ram either. It has nothing to do with the quality or reliability of the mains supply; ECC increases reliability via protecting data integrity from bitflips caused by cosmic rays etc.

  Hm, I keep my server in the basement, I wonder if 6" of concrete makes any difference to cosmic rays?

> Those are pretty awful by current standards Oh, fully agree. My base spec M1 Air destroys them in anything single-threaded. I got them because I wanted three nodes to play around with various things requiring HA, and I didn't want to just virtualize that. That said, they _are_ virtualized. Every server I have runs Proxmox, with templated VMs built from Packer + Ansible. I'm currently in the process of shifting K8s providers; right now they're running k3os but since Rancher has killed that, it's forever stuck at v1.21, so I'm shifting to Talos. I have the Terraform for them working fine, just need to set up a PXE server so they'll pick up the desired static IP when being created. > you aren't really gaining anything from ECC ram either Sibling comment to mine addressed this; to add on, I disagree. Cosmic rays aside, there's a ton of EMI inside a computer, and anything I can do to help prevent data corruption is a win in my book. Torvalds agrees, if that carries any weight with you.

  A friend of mine built a k8s system with Raspberry Pis, back when they were cheap and available, which burned very little electricity and produced no detectable heat.

    Yep! I have an RPi 4, and at one point it was running Hypriot [0] on it, with some lighter containers being handled by it instead of the larger x86 nodes. I'm pretty sure I also had it running as part of a K8s cluster for a brief time. [0]: https://blog.hypriot.com https://blog.hypriot.com
