wrong forum section. this should have been posted in the new build area.

that said: a few comments listed in order that you listed (generic advice, i'm not clicking links here)

-no comment
-haf is good but overrated. antec 900d is just as nice.
-why phenom? its hard to recommend anything but an i7 nowdays. prices are reasonable and its a powerhouse.
-you don't need a special heatsink if you plan on running stock. even with i7. good thermal paste is a great idea though.
-have you thought about raid 1? just an idea (but trust me, its nice if one fails!)
-why 8gb? i have 6 and i've never used more than 50%.
-no comment
-do a power consumption check on a website (search google). 750 sounds reasonable for what you listed (but double check this).
-no comment. (i use strictly nvidia so i can't give feedback)
