Begin by turning your G4 Cube over on it’s top. You will want to place the computer
on a soft cloth or a rubber mat to keep it from sliding around while you perform this
upgrade. A mouse pad works well, just be sure to not scratch the top of your Cube.
Press inward on the core retaining handle and release the locking mechanism as shown.
Remove the core from the outer shell and place the shell in a safe location so it will not
be in the way or get scratched. Press the core retaining handle back in, locking it in
place and turn the core over so the heatsink is facing up as shown.
Remove the 8 Torx T-10 screws as shown, note that screw #5 and #6 are longer than
the others and extend all the way into the latching mechanism. You will need to replace
them back into the same holes when completed.
