(case is a personal choice, but there are plenty of good options in the 50-100 dollars range, and a completely clear case like this one is fucking pimp).

(I have revision 1 on my core2 system, works great, no issues in 4 years) Stock CPU fans are barely adequate.

(matter of taste and what you want, ive used both basic crucial ram, which is great as well as performance ram like the corsair dominator sticks in my current PC, I honestly couldnt tell you a difference) the board supports 800/1066/1333 DDR3 ram so the amount/speed is personal tase, doubt you would see a difference in 1066/1333. DDR3 is triple channel, so you want to have at least 3gb, distrubute evenly into the triple channel slots.

Overspent by a 100 bucks. but you could probably downgrade the Proc/Mboard/PSU probably dont need 6gb ram, I wouldnt skimp too much on the video card. Also, if you do more digging for deals, you can probably shave 100 bucks off the cost.
and I dont know what you already have and intend to salvage from your old system (HDD's, DVD-rw, case, windows etc)
