PVE running on a pile of e-waste. Most of the parts are leftovers from my parents’ old PC that couldn’t handle Win10. Proxmox loves it. Even the 10GB mis-matched DDR3 memory. The only full VM is OPNSense (formerly pfSense), everything else runs inside Debian containers. It only struggles when Jellyfin has to transcode something because I don’t have a spare GPU.
