Check my signature for the specs on what I built. It may be more than you need but at least gives you some ideas. I have a 1000W power supply. I plan to upgrade to a GeForce 580 series graphics card in the near future. SATA drives are a definite must have as they are essentially the default drive type for most systems these days. You can easily overclock your CPU as I have if you get a decent heatsink and fan. If I were you I would get two hard drives instead of one huge one. I have three on my system (one for WinXP, one for Win7, and one for data storage). I would suggest two 500 GB's. Defrag would take forever on a TB drive. I buy most of my stuff from NewEgg. TigerDirect is also good.
