Be careful with the cable to the buttons on the front bezel.  
1. 4 Screws for the base support<br>
 
2. 3 Case Screws, 2ea in lower corners and 1ea behind base support area<br>
Be careful with the display cable - the metal case with the PCB's is not mounted to the Display frame.     
3. Using a plastic spudger, separate case from bottom to top<br>
4. Remove all screws from metal sheld<br>
