I’ve finally gotten around to swapping all of the parts from the new cabinet to the original cabinet. Here are a couple of photos of my progress:

The new cabinet, completely gutted. The original cabinet, filled with parts. The back of the new cabinet, stripped of parts.
The back of the original cabinet, fully outfitted with parts. A new boardset installed in the original cabinet. The back of both cabinets, once the parts swap was complete.
