First, you need to prepare the case. If you pay attention, the case has a rectangular opening measuring 6.250 in x 1.750 in (15.87 cm x 4.44 cm) to accommodate the plugs available on the back of the motherboard. This hole is covered with a finishing that has smaller holes matching the plugs availabe on the motherboard. You need to check if the plugs on your motherboard match the holes on this finishing. See Figures 8 and 9.

In our case, the holes on the case didn't match the pattern of the plugs available on our motherboard. So we needed to remove the finishing that came with our case using a pliers and install a finishing that matched our motherboard. Motherboards usually come with a case finishing that match the pattern of its plugs. Cases usually come with a set of most common finishings.
