Be careful when separating the bottom panel from the front casing to avoid breaking the three cables connected to the motherboard (two on each side and one in the rear).
Using a spudger, separate the back panel from the front casing by gently prying around the panel.
There are many clips along the hinge of the case, so it is recommended to work your way along one short side and the two long sides before finishing the last short side.
