Firstly, you may want to go with the sugo sgo5b case a pop out cd tray for the dvd drive as the push in style leave nasty looking gaps.
Also you can fit a bit more powerfull card such as the 4850 or 260, in that case with some inventive cable mangement.
Other than that looks ok, the board can handle a 1066 fsb cpu btw, only the ram is limited to 800
