I’m already very familiar with the AMT portion of vPro, all three of my Proxmox nodes have it enabled and locked down. Really handy to get in there when needed. The KVM route is rather expensive as I would need one that supports at least 5 systems.

vPro’s out-of-band management is the entire reason I use it, because my little lab is all the way in the basement, where I would have to cross the treacherous lands of scattered children’s toys.
