motherboards. Other cases don’t use the standoffs because the screw holes are elevated
to keep the bottom of the motherboard from touching the case. For these cases, use
screws to connect the motherboard to the case.
3. Place the motherboard inside the case (see Figure 3-46), and use screws to attach it to
the case. Figure 3-47 shows how you must align the screw holes on the motherboard
with those in the case. There should be at least six screw sets, and there might be as
many as nine. Use as many as there are holes in the motherboard. Figure 3-48 shows
one screw being put in place.
4. Connect the power cords from the power supply to the motherboard. A system will
always need the main P1 power connector and most likely will need the 4-pin
