Question 3

List three reasons you should use matching form factors for the motherboard, power supply, and case.

Accepted Answer

Using matching form factors assures you that: The motherboard fits in the case. The power supply cords to the motherboard provide the correct voltage, and the connectors match the connections on the board. The holes in the motherboard align with the holes in the case for anchoring the board to the case. The holes in the case align with ports coming off the motherboard.
