How to Open a Desktop Case
Caution!
Whenever you open the case or work inside the computer there is
danger of static electric shock. These shocks can permanently damage
your equipment. Always ground yourself by touching the system
cabinet before touching any internal component. We strongly recom-
mend using an antistatic wrist strap attached to cabinet ground.
To open a desktop case:
1. Turn off the monitor and system unit power. Unplug the AC power
cables and disconnect any other cables attached to the back of the
system unit.
2. Remove the plastic bezel from the back of the case by pulling it
away from the case.
3. Unscrew the five mounting screws at the back of the case that
hold the case cover to the system unit chassis.
4. Slide the case cover back and up. Be careful not to snag any
cables or connectors inside the case.
5. Set the case cover aside while you work on your system.
6. When through, reattach the case cover, screws, bezel, and cables
in the reverse order.

locations, and how to remove a desktop PC’s
cover.
