If you have a little extra
Newegg.com - OCZ GameXStream OCZ700GXSSLI 700W ATX12V Power Supply 100 - 240 V - Power Supplies
Has a rebate that lowers the price to $79.99.
Things I see missing:
-Sounds card (thinking you're gonna use the mobo integrated one)
-DVD player/burner
-Cooling compound for the CPU/Heatsink
And also while installing Vista, do it with only 1 RAM stick, it goes stupid with 2 and won't install, after installation shut it down and put the 2nd one.
