Can both side covers ff a computer case be removed? I can remove one of the covers dead easy just by removing the two screw at the back. But When I come to remove the other side, i cant get it off with just removing the two back screws. The reason I want to get it off is beacuse there is a screw with the bottom pointing up into the case. I think the head of the screw is underneath the case cover i cant get off. Any help would be nice and I would be grateful. Thanx
