I just completed my first build and noticed that my motherboard Asrock H97M Pro4 doesn't fit all of the standoffs on my Corsair 350D case. The problem is that the board seems to be too narrow for the case (can see through the cut out in the back plate of the case when the motherboard is installed). The two corner standoffs don't fit the motherboard, so there is no support on either of the right side corners. Is this board an odd shape? I'm worried about warping due to these corners not being supported..any suggestions or thoughts?
