I recently picked up a Pac-man cab in fairly good condition. The plywood is chipped off near the bottom on one side panel, but it's nothing a little bondo can't fix. The horizontal panel on the very top of the cabinet (particle board) looks really bad though. It's swollen and the paint is flaking off. I'd like to replace it, but is it possible to disassemble the cabinet safely? Otherwise, what's the best way to replace or fix this top panel? I'd appreciate any suggestions.
