First off, the motherboard is a GA-P35-DS3L (new, everything was in the box). I don't really think case is necessary, since the problem isn't fitting it, it's because I don't know anything about placing the board into the case. The board isn't actually touching the bottom of the case, because the CPU fan and the bottoms of some other other prongs are holding it up, but I'm pretty sure there's more to it, especially because the video card has that piece of metal at the end that hangs over the edge of the board. Is there something else that goes under the board, and if not, what happens with the video card?
