As for them being LOTR machines, the only artifact of that is the knowledge that the person I got them from isn't lying, and a small sticker that could easily be faked. (It's just a simple sticker, not an anti-theft or anything.) No original software or anything left - even the HDs are significantly newer (SATA card with SATA drives - which didn't exist when LOTR was being made.)

Yes, server PSUs are rated to run at that wattage 24/7.

No need for a patch panel, I'm just on the lookout for a rack-mount 16 or 24 port Gigabit switch, but just waiting for a deal, no hurry. (Don't even have a rack yet - I'll be remodeling the basement at some point and putting an enclosed rack in at that point.)
