hi rdunnnill, im a spray painter so a bit of body work not to hard for me what i did was cut the proprietary front panel of the 4550 backing board, most screw holes lined up with both mother board only the 4 that hold the heatsink didnt line up so i hammered toughs four down plus 2 others and drilled in the correct spots and put spacer in between to get the correct height and the 4700 proprietary front panel connector sits nicely in the same hole in the 4500 case
so now if i want to take the mother board out i dont have to unscrew anything as the backing plate in the 4550 just clips in
do you think 500w is enough even if i put in 3 fan
thanks for your reply
