Hi. Since yesterday i selfhosted all my stuff with a raspberry pi and two odroids. Everything works ok, but after i read about a few apps that are not supported by the arm-architecture of the SBCs and about the advantages of the backup-solution in proxmox, i bought a little server (6500T/8GB/250GB) to try proxmox.

Installed proxmox, but now - before i install my first VM - i have a few questions:

a) What Linux OS do i take? Ubuntu Server?

b) Should it be headless?

The server is in the cellar of my house, so would there be any advantages of installing an OS with a GUI?
