The Computer Case houses all the computer components. The first step is to slide the side panel off the case. Most side panels are secured by several screws. Inside the case are various regions that perform different functions.

The Power Supply which will typically come installed in the computer case supplies power to the computer via various sized Power Connectors and one larger ATX Power Connector.

The Motherboard Pan keeps the Motherboard in place using Brass standoffs or plastic connectors.

The Full-Height Drive Bay holds the computers CD-ROM, DVD, and CDRW drives. When these devices are installed the plastic plate on the outside of the computer case is snapped out to allow the computer user access to these devices.

The Half-Height Drive Bay contains the computers Floppy Drive, Hard Drive, as well as any other Half-Height devices E.G. Zip drive.

The PC Speaker issues various noises that give audio cues to the inner workings of the computer. For example when the computer first boots up, it emits a beep after successfully completing its self-test.

Your Computer case should come with a little bag filled with screws.

• Chassis screws- These are little screws that are used to hold your computer cards in place.

• Motherboard screws- These are used to fasten the Motherboard to the Motherboard pan.

• Standoffs-These are either Brass or Plastic and are used to hold the Motherboard firmly in the case while at the same time keeping it from touching the actual metal case, which could cause a short in the motherboard.

Make sure you set the power supply to the proper voltage. 110v in the United States and 220v in other parts of the world.

You might have to install the little plastic feet on the bottom of your computer case. If you do, do it now.
