Remove all the pluggable screw terminal connectors from the boards and set them aside for later.

Take the MUSCLE BOARD, and install 4x M3 6mm Male x 6mm Female Nylon Spacers and 4x M3 12mm Female Nylon Spacers as shown

Remove the protective backing from the self-adhesive thermal pads on the rear of the 2x 32x40x11mm Heatsinks Carefully stick the heatsinks to the MUSCLE board as shown.

NB: Make sure to line the heatsinks up within the printed boundaries on the PCB and ensure proper adhesion for optimum thermal performance

Add the Brains board onto the stack. Tighten it down using 4 x M3 12mm Female x 6mm Male Nylon Spacers as shown.

NB: be very careful to align the two boards together and ensure the interconnect Pin Headers make a solid connection. Also make sure the connector is not offset / bent / incorrectly plugged in.

Install the USB and Motor Side Panels and attach using 2 x M3 x 6mm Screws per side

Install the A29 Button Cap onto the Reset Button on the front side of the Brains Board

Install the Front and Back Panels and attach using 2 x M3 x 6mm Screws per side

Install the Bottom Panel using 4 x M3 x 6mm Screws as shown

NB: If you check the bottom plate, one side has two lines running over it. Attach the bottom plate so these two lines point inward, lining up with the plates you installed in step 5

Attach the 60x60x10mm 24v Fan using 4 x M3 x 16mm Screws and 4 x M3 Nuts

NB: Check the airflow direction of the Fan itself: Ensure it will be blowing downward onto the heatsinks, pulling cool air into the case from the top. IE: Mount it so that the side of the fan with the sticker, faces toward the heatsinks.

Plug the fan's Power Lead into the Fan Power header on the Brains Board. The image below is shows the suggested wire routing (Pictured as if the top cover is invisible)

NB: Check your fan wiring polarity. Make sure to line up the RED wire on the plug with the + symbol on the board, and the BLACK wire with the - symbol.

Attach the top cover / fan sub-assembly from the prior step to the BlackBox using 4 x M3 x 6mm Screws

TIP: Before closing the TOP Panel, you might want to check section 2.1 of the documentation, if you need to change any jumpers it's easier to do before closing the top.
