I’ve tried proxmox! Don’t currently have any hardware to run it but excited to do it. Part of the reason I don’t want to put it on the mini PC is that I can’t connect 3.5" drives over sata. I want to use the PC I plan on building as a combo server/NAS.
I am planning on a lot of services, but we’ll see about the rack of servers.
I do the same. I have Debian with KDE and Kodi autostart on boot. Use Kodi most of the time but can tab out if needed.
