7) This one is a bit more esoteric so I'll give you a fairly general answer. You will want to focus on two main things: CPU and RAM. For RAM, the general rule is 2GB for the first copy and another 512MB for each additional copy you want to run on that box. For CPUs, any of the 2.3GHz or higher Core2Duo chips or Athlon X2 6000+ chips should be fine for running 3-4 WoWs. You could probably get away with less but not at 30FPS for all 3-4 copies.

P.S. Yes, I'm trying to make a point with the answers to 1-6 above.
