Hi! So I'm considering...maybe having an NPU or something similar to be hooked to my proxmox server, which runs in a mini PC. It's a EliteDesk 800 micro form factor. It has a Core i5 8500 CPU, which at the moment of purchase was good enough for live encoding HEVC video on Jellyfin...that was my main concern back then. But I'd like to consider the possibility of hooking maybe some docker instances or other containers to some local-only AI acceleration. Is there any NPU or cheap GPU I could hook on USB to this proxmox server to run? Has it been done before?

Thanks!
