if i was trying to budget build something right now thats roughly what i would do. i am running that case and video card right now. running a sandy bridge I5 and a older asus lx board.
oh.. there is like 60 bucks worth of rebates in there too. i didnt list em. didnt list win 7 either. if you dont have a copy you could get one there for like 100 bucks.
