I have the same model. The idiot that I bought it from decided to pack the keyboard on edge underneath the main unit so it arrived with a bit of a kink in the chassis and a cracked case.
If you have a lazy Saturday coming up, it might not be a bad idea to try it (look at some of the youtube fibreglassing tutorials).
It would be great if you can show that glassing is a viable way to restoring old stuff while keeping the same period look.
