 + 
 +To remove the backside: 
 +  - Remove foot (1 screw) 
 +  - Locate the two screws holding the backside. One is under the "E" in the "CE" symboland the other the //wifi key// white box. To reach those screws, you can either remove the backside sticker (harder but cleaner), or simply write down the wifi key and pierce a hole in the sticker (much easier). 
 +  - Remove those screws. 
 +  - With the guitar picks, start from the oval hole holding the foot at the bottom, then work your way along the bottom, then the sides. 
 +  - Holding both halves of the case, jiggle them around slightly to help detach them. 
 +  - Eventually you'll separate the halves. Nothing is attached to the backside.
