Using an old organ cabinet saves a lot of time if you can find one that is roughly the same width as your arranger (61 keys are easier to fit into these old cabinets)...many years ago, a friend of mine built his Roland E-10 into an old Yamaha Electone A-55N shell that worked out quite good aesthetically...but it still sounded like an E-10, which wasn't exactly breathtaking, although passable.

His wife had pressured him into making it ("Honey, the E-10 looks too much like a musical instrument"), but it still worked out okay in the long run, as she and the instrument disappeared in the divorce, and he ended up getting a sweet deal on a fully loaded 9000 Pro that he could leave unaltered.

I asked him, "Bad divorce?"

"Nope, the divorce was great,” he said, winking at me. “It was the marriage that sucked.”
