SGI Origin side skins

[Jules Richardson]

Does anyone know how to remove the side skins on an SGI Origin 
(specifically a 2200 deskside cabinet). The manual mentions removal of the 
top and front, but says that the sides are more tricky and to contact SGI 
for the procedure.

I'd like to remove them as there's some minor paint splatter on them, which 
would be much easier to deal with off the machine.

I see there's a screw at the bottom of the machine on the rear edge (much 
like the one for the front which releases the front skin), but removing it 
doesn't seem to let the rear plastic molding drop in the same way, and I 
assume this needs to come off first.

cheers
