Computer Case - ATX

Other Case Designs
Some manufacturers of cases have made efforts to make cases "screwless". With this design, you usually take hold of the bottom of the front of the case and give it a nice solid yank. The front then pulls off. It is my experience that this usually requires a few tries and some muscle. The case is pretty durable. After you pull off the front, the sides lift and slide off and you just lift the top off. Your case comes apart in four pieces. Other such cases have a similar design.

Static Electricity
Static Electricity is no joke. All of your PC's components are sensitive to static electric charges. It is very important you ground yourself by touch the frame of the case periodically through the installation process. It only takes a second, so do it often. Remember to ground yourself before you remove all parts from their protective anti-static bags.
