I would suggest not getting a cheap MB, since it is the most importaint opart of your computer.
Go with Windows Vista Home Premium.
Good deal on the Hard Drive
Nice CPU, L2 cashe is nice..
It's a nicegraphics card, but if you wanted something cheaper, the GeForce 8600GT's get the job done too, for half the price, I am currently using a GeForce 8600GT 256Mb RAM, and the new 8600's have DDR3 ram, so look into those as well.
Also, with Media Center you can record LIVE TV, so you might wanna think about a TV Tuner Card, you can hook up your Cabel, or Sattilight to your Computer and record shows.
Everything looks good, I would just say to Upgrade your Motherboard
Also, before you order, go to TigerDirect.com and look at there Barebones kits,you can get some great deals there, like Free RAM and stuff, so just something to take a look at. (Barebones = MB, Case, Pwr supply, CPU, and RAM)
Here is a BareBones kit, with a kick *** MB
http://www.tigerdirect.com/applications ... o=3905991&CatId=2405I think it might be a little to much, but it has a 500Gb SATA HDD, but on the down side only 2Gb of RAM. It has a better Power supply, and the case is a lot better too.
But another 2Gb of the same ram is only 24 bucks,

But yeah, just make sure you dont cheap out on teh Motherboard, remember with computer's it is only as fast as the slowest part, sure the CPU kicks ***, but if your MB has a slow transfer rate (Front and Backside bus) then it will slow down. People always forget about how importaint the MB is =-p
Hope this helped
