Two 10 mm T6 Torx screws on either side of the RAM slot.

Four 14.5 mm Phillips screws along the hinge.

Lift up at the rear of the case and work your fingers along the sides, freeing the case as you go. Once you have freed the sides, you may need to rock the case up and down to free the front of the upper case (there are some hidden plastic clips that need to be clicked off).
