Carefully guide the joysticks through the front case and lift the motherboard out.

The motherboard is held down by two clips. One between the motherboard itself and the right trigger assembly, and one between the motherboard itself and the left trigger assembly. Gently push on either clip to release the motherboard from its restraints.

Do not completely remove the motherboard. There are four soldered wires tethering the motherboard to the vibrator motors.
