How to Open a Tower Case
Chapter 1 - The Big Picture
The figures opposite show the plastic bezel, screw
locations, and cover motion for a tower 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.
Opening a tower case is almost identical to opening a desktop case.
To open a tower 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 rear of the case by pulling it
away from the case.
3. Unscrew the six 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, taking care not to snag any
cables or connectors inside.
5. Set the case cover aside while you work on your system.
6. Afterwards, reattach the case cover, screws, bezel, and cables in
the reverse order.
