I am currently in the middle of putting together my recently acquired parts and I am having trouble installing my motherboard (ASRock H97M Pro4) into my case (NZXT S340). The case has two standoff screws already sticking out which the motherboard is on right now, but I can't figure out where to screw anything else into. It came with a single standoff screw but I don't know what to do with it - I tried to screw it into the one screw one with an opening on the other side, but it doesn't reach. Does anybody know how to install it? Thanks.
