Computer cases are produced in a variety of form factors. Form factors refer to the size and shape of the case. Prepare the area before opening the computer case. There should be adequate lighting, good ventilation, a comfortable room temperature and outlet power near the working area. Use an antistatic wrist strap to prevent physical and ESD damage to equipment. If you don't have antistatic wrist strap, you can touch unpainted portion of the case or any grounded metal to discharge the static from your body. Small containers can be used to hold small screws and other parts as they are being removed.
Unpack the computer case and follow the instructions on the user manual or manufacturer's website to open the case. Most modern computer cases have Thumbscrews so that users can open/close the case without using screw driver. Firmly loosen the screws to open the side panel of the case.
Most computer cases are opened in one of the following ways:
- The PC case cover can be removed as one piece.
- The top and side panels of the case can be removed.
- The top of the case may need to be removed before the side panels can be removed.
Some computer case have sharp edges, always handle computer case with care.
