Can't physically install my X99 gaming G1 wifi motherboard into my Rosewill THRONE-G-Window Gaming ATX Full tower case. There were no screws supplied with the motherboard so I had to use the ones from my old build. However I simply cannot screw in the motherboard. The screws are too short, and it almost seems as if the holes are lined up incorrectly. By that I mean I have to force the motherboard towards the back of the case to get all the holes to line up. Is that normal? I don't remember that happening on my first build. So what exactly should I do to get this installed?
