First use a thin metal spudger to remove the four self-adhesive plastic dots covering the screw holes.

Remove the four Phillips screws holding the cases together. You'll need a thin-shafted screwdriver to remove them.

Ventilation holes abound in the top and rear outer cases. Such a Swiss cheese case design allows the chumby to cool off without the need for a fan.

There are no screws in the bottom case; it is held in place when the cases are fastened together.

Pull the rear case away from the chumby to reveal the spiffy internals.
