Thanks for the detailed response Hap.

For those who have not seen a G4 Cube close up (including me before I bought it), the acrylic plastic case is one solid piece. I thought the four sides mated with the top plate in some way as it appears in pictures of the unit but no; it's one solid piece. No wonder it''s notorious for cracking. It hangs by those two screws (found that out when taking it apart to clean) and one can see faint mold lines right were the screws are making it easier to give way to the added stress. I'm very happy for it to be in any presentable shape.
