Did you already order the parts? The motherboard only supports up to 333 MHz on the FSB, so you can't really ever upgrade to an Athlon XP 3200+ if you wanted to. Plus, that's expensive for a motherboard that doesn't go up to 400 FSB. I got mine for at least 30 bucks cheaper. Also, for the heatsink and fan, I'd recommend the Coolermaster Aero 7 or Aero 7 Lite. I think it would work better.
