careful here... the right side has 1 or 2 plastic snaps along the slide. I had the most problems with the one in the middle of the right side. first make sure you don't damage the power switch on the front right side by lifting forward then up. The ever so carefully push just a little to the left. This might help a little. It's tricky. Once you have it off I'd recomend cutting off that plastic snap in the middle of the right side. Also don't use ghost clips on sensor c, the one in the back by the middle screw. if you have the wrong model it will not fit. Trust me i busted my slimline doing that. use the tape method instead. Best of luck.
