Alesis Andromeda A6

Hi folks,

In the process of cleaning the mod wheel I tried to pop open the side 
of the A6 by unscrewing the bottom 3 screws on that side and pushing 
out the side panel. Unfortunately, the side cam off but I discovered 
that it was held together by 6 screws and I damaged the screw holes. 
Bummmer! I am surprised that the plastic broke so easily because I did 
not apply real force at all.
Anyway, I don't want to break more stuff and would like your advice on 
how to open the Andy in order to reach the mod wheel housing.

Thanks in advance,
Ra
