'move the motherboard' ????
what the hell are you guys talking about? mobo's have specific mount points that only allow for a 'smigin' of room to alter its position. if he cant get screws to hold the cards in place, then most likely he's got a crappy case and needs to get a new one. Even being a few mm off will allow the screw to hold the card. if its this noticable... theres a design flaw in the case.
