I buying HW to make a PMVE PC server, but im not shure about the motherboard, someone had PMVE 4.2 working out of the box with any 1151 motherboard? if not im going to buy an older, 1150 and go with that... but 1151 has more value.
Most Hardware should work. It is Debian. So if Debian is running PVE will too. Important is that you buy an hw without secureboot, or an hw where you can deactivate it. And buy no HP DL 380 up to G8 that make a lot of problems with firmware.
