4. Face the front of the chassis. Use your thumbs to press in both cover
release latches while pushing the cover backward. Move the cover back
about an inch, and then lift it straight up off the chassis.
If necessary, use both hands and work one side at a time.
5. If your chassis has a support beam attached to it (see Figure 4-2), pull up
the front end of the beam until it snaps free from its fastener. Lift the front
of the beam until the hinged tabs on the back end of the beam clear their
slots.

Replace the computer cover and support beam on a desktop or mini tower
chassis as follows:
1. Check all cable connections, especially those that might have come loose
during your work. Fold cables and unused connectors out of the way so
that they do not catch on the computer cover or interfere with airflow
inside the computer.
2. Check to see that no tools or extra parts (including screws) are left inside
the computer.
3. If you removed the support beam from the chassis, slip the beam’s hinged
tabs into their slots (see Figure 4-2) and lower the beam. Then place the
support beam
