Solid. You could save a few dollars with another ASRock z68 mobo that comes in at $85. The Hdd is the lower end of the WD series (the Black being the top end but more expensive and more dependable). CD/DVD RW? As for the gpu look at the Toms February review and note the AMD options.
If you really want a modular PSU then I think I would take this before the BP550:
Rosewill Hive 550W 80Plus Bronze Modular $70
http://www.newegg.com/Product/Prod [...] 6817182131 Uses the same internal design as the OCZ ZS Series 550W, which has been positively reviewed (as have the other members of that series).
If you really want an option to SLi in the future you need to change that PSU to a 700~750w PSU that delivers ALL the power in the 12v rails, to make sure it won't run into problems.
