Okay, here it is:
Case - Cooler Master Storm Enforcer
Mobo - ASRock Z77 full ATX etcetc
PSU - the one you suggested
CPU - i5 3570k
GPU - Radeon 7870 Gigabyte GHz edition (will buy another one later)
HDD - WD Caviar Blue 500GB 7200RPM Drive
CPU cooler - CM Hyper 212 Evo
Optical drive - Asus dvd/cd burner, the standard blah.
Kinda feel like I'm missing something because it's so cheap. (896)
Get an Ares kit if you arent already. Low profile so it wont conflict with a heatsink larger than the EVO if he ever upgrades to a Noctua or something.
You buying an OEM or Retail copy?
An OEM key is around $100 but can only be used on the one machine (the motherboard to be precise). The Retail key can be used on multiple machines but costs a fair bit more (~$230 I think).
