Remove the remaining four, 5 mm screws.

Using a plastic opening tool, gently pry open the front cover.

After you remove the front cover, the motherboard should be exposed, along with the two port boards.

You can now lift the motherboard out of the frame while simultaneously disconnecting the wires on the underside.

Remove the four, 3 mm screws and disconnect the red and black wire from to the motherboard.

Unscrew the six, 5 mm screws to disconnect the copper heat pipe.
