I have an ASUS M5A78L-Plus mobo, trying to fit it into a Linkworld Ninja 2 mid tower case. I thought it would fit fine, but the screw holes don't line up, except for 2 of them, but to make them line up exactly, it feels like it's putting too much pressure on the mobo. Needless to say, it feels wrong. I know I'm lining it up correctly, everything lines up fine with the i/o shield and pci ports, but the screw holes don't line up at all. Do I need a new case...?
