After your fans are out and your case is open it's time to install the motherboard. The motherboard attaches to the case by 5 or 6 case screws. These screws should come provided with the case. A spacer goes between the case and the motherboard so it doesn't sit in the side of the case. After the screws are tightened and your motherboard is secured it's time to connect the brain of the computer - The Processor!

       But before you go... attach the PSU to your case by a few screws just look at the case page for the correct orientation. After it is in place, connect the PSU to the On/Off switch inside the case. (refer to the manual that came with your case)
