I tried to do that on my 9343 and pretty sure I ended up breaking one of the clips on the aluminum case. I got it back on and after reseating it a couple of times there's no longer a visible gap once I get all the screws it, but there's a spot on the back of the laptop where I can press down and here a slight clicking noise, like a latch is trying to catch somewhere but can't.

Just saying, removing some of these things can be more difficult than the Youtube videos or internet guides would have you believe.
