Well, I only had mine (a GS5) apart for a short period in order to fix smoke unit connections that were reversed and the attached photo is one of two I took. I did not find the main board sloped as yours is, or any pinched/rubbing wires, but just discernible in the photo (lower right corner) is a screw near to where the boiler speaker screws are, which appears to fix the board to the chassis. Do you have a screw fixing there or is the screw missing? It appears to be on the opposite side of the board from the side your photo is taken.
I agree that the assembly quality of these is not what you'd expect from a VL model.
