Link is dead. I guess it's for the old remote. Which is the one I wanted by the way...

I managed to take the back off a previously wetted keyboard (A1314), not my doing. I took the board out and the back off before washing. It's drying as I type this. The hardest part was getting it started. I used a strong thin knife edge to slightly lift the white back at one end. I ever so slightly marked the plastic and aluminium. As soon as I had room to push a smallish flat screwdriver in I did. Be careful to put it in flat so as not to damage the clastic or the aluminium grill with the edges of the screw driver. Giving the screw driver a rotation twist I heard some glue pop free. While applying consistent but not too forceful lifting pressure on the white plastic I continued to sweep back and forth with the screw driver twisting to separate the part. I noticed there were key places where the glue was holding strongest and they were best places to twist. I moved from one end to the other in a couple of minute. Remember, be patient! Don't bend the plastic too far and gently twist the screw driver so...
