This took way longer than should have (see the full post up on the Arcade Cabinet project here). It was so simple once I borrowed my daughter's jigsaw. I simply had to modify the shape and size of the default holes cut for the cabinet, and shim up the bottom edge a bit. Came out looking pretty decent. Still need to install fans and a power supply, but can now actually run the switch that senses the coin entry off the I-PAC mini control board! Read on for the full ordeal, though it was really pretty painless.
