4Loosen the two thumb screws on the right side of the back panel. The first time you loosen these screws you’ll need a flathead screwdriver. (These screws do not detach; they’ll stay on the side panel loosely until you tighten them again.)
5Stand behind the computer, and place one hand on top of the chassis.
6Grasp the handle (A) with your other hand and pull the panel towards you until it stops.
7Lift the panel up and out. Set the panel aside.
