Well, first off get the ABIT KT7-Raid. Its just a little bit more money, and you get $200 worth of stuff (ATA100 Raid), which would cost $200 to buy seperatley.
Motherboard: Abit KT7

RAM: 128MB (Considering PC100, since its cheaper than PC133, and I'm not sure that there will be a very noticeable difference)
VIDEO CARD: Maybe a Matrox G400 (Allows dual monitors with one card), Maybe a cheaper card. I'm not a big gamer.
