2. Press in the two securing buttons until the cover is free to swing up.
3. Lift the cover, from the back, pivoting it toward the front of the system 
unit.
Four plastic hooks on the inside of the front part of the cover secure it to the 
chassis.
Before you reinstall the cover, fold all cables out of the way so that they do 
not interfere with the cover or with the proper airflow inside the system unit.
