Nice processor, good reviews too. But a tad expensive for my taste. Try this processor. It is only $357. You can save some money on the RAM if you get two of these. I am not a big fan of the case you chose, I think there are just too many drive bays. Maybe this. That has a 500W power supply. Personally I love this case. Lastly, what are you doing getting a 120gb hard drive? I would recommend something with more gigs. Better to have too much hard drive space than not enough. Try this. It is your choice and your money, do what you want with it. I am happy with building a computer around $500-600, but the only difference would be some watts, 1 gig of ram, and .2 ghz.
