I’m fairly green at self-hosting, recently upgraded to running Proxmox on an old PC from OMV. A fairly simple setup for Plex, Nextcloud, PiHole, and some docker containers. I have an old Ryzen 5 2600 I’d like to replace the current CPU with (an even older FX-8350), but I’ll need a new motherboard with an AM4 socket.

In sourcing a new mobo, are there any features or other considerations I should keep in mind, given its sole purpose of being a server now, rather than a general purpose PC? Or just try to find something relatively inexpensive that’ll get the job done?
