Now on to the motherboard mounting plate. You'll need to countersink the holes, these are marked in the drawing.

Attach the screen mounts. Use mini spring clips to hold the pieces together while gluing.

Insert the M2.5 x 10 CSK screws, fix with a washer and two screws - to raise the motherboard up slightly.

Screw in the M3 x 15mm Hex Spacers.

Install the motherboard (use M2.5 lock-nuts) and other components.
