Ok, I have a micro atx mobo and a defender case. There are 6 stand off holes that are on top of these little bumps. Then there are a bunch of other standoff holes that are not on top of these bumps. My motherboard requires standoffs that are both on top of these bumps and not on top of these bumps. What do I do? Do I put two standoffs on top of eachother? It appears to be the same height as a standoff with the bump when I do. Or do I not use those non bump standoffs?
