Pretty much all of mine are just tiny/mini/micros. The stack of 6 or so in my rack power everything I run (aside from my desktop, but I do have Linux vms and a Mac mini for app builds).

No issues so far.

Storage is all on my NAS, one for things like media server content, my dev work, pictures, etc, and one that’s a backup to that NAS. Only thing remote is my second level of backup.

8th gen Intel and up is pretty great for proxmox IMO.
