Hi, I recently recieved my Corsair 300R case and my Asus M5A97 motherboard, I'm at the stage of mounting the motherboard inside the case. The case comes with 9 holes and they're in 3 rows of 3, the central hole has a standoff already screwed in. When I slip the motherboard into place the standoff will fit in, but, the other holes don't all line up, maybe one or two. I have tried putting the screws into the ones I can in hope that it will move the motherboard into place, that didn't work. I've tried pushing the motherboard more into the corner (the holes are halfway there) - I've got no idea how to line them up, all help is appreciated, thanks.
