40R7H0 was created to add ortholinear support to 40700 cases. Given that 40700 uses a 14u wide design, it lends itself to an ortholiner PCB more readily than some other Trash Man boards (see Minibaen).

40R7H0 features a unique 14u layout with columns of 1.5u keys flanking the left and right edges. This allows for a centered 1u column in the middle that supports a rotary encoder in the top row. The bottom row supports multiple spacebar options including 7u and 10u bars with 7u plate-mount stabilizers (such as the one included with DCS Classic).
The PCB is blue with a while silk screen. The only markings on the front of the PCB are the box denoting the location for the rotary encoder. The back of the PCB includes the name of the board in spray paint stencil font and the characters Reki and Langa from the anime series Sk8 the Infinity.
