I just bought a back up (extra reserve) PC. Got a refurb IBM ThinkCentre 2.8 HT, Win XP Pro, CD on Ebay for $90. Added some extra memory I had sitting around. Nice system for the money.
The price was too good. I could not get close building one. I am going to throw in one of my old drives and put the Beta of win7 on it.
Good point, I will have to rethink that source vis-a-vis refurbed units perhaps.
