some thing I'd change is the video card.. 9800 XT is sorta pointless, save some money and go with a 9800 PRO if money is an issue, if it isnt then go for a new gen video card like the x800..
Id drop the 1gb of RAM, because no system is going to use that much RAM right now AND the price of RAM is only gunna drop, so you will pay less to buy it later..
I'd also scrap the idea of 2 h/d's, thats just asking for excess power waste and thrashing between the drives, pointless if you ask me, especially building from scratch when you can get one 160 for prolly cheaper then both of those 80's..
Everything else looks good.. Should last you a few years for sure
