Thanks for the feedbacks.
I'll see what I can do about the PSU, it comes stock with the case.
Any idea on a good alternative for 1GB GT220 DDR3? I think over here they're about the same price (or at least the difference is negligible) with a Powercolor 4650. I might add more and get the 4670. 9600GT is out of the budget
Wont do much heavy gaming (like Crysis, etc.), would the 4670 be good enough?
