My first DIY modules - starting a Kosmo format build

For one thing they only allow for 6mm clearance at the top/bottom

In the Kosmo Specifications thread, it is said :
PCB
• Maximum recommended height 175mm to clear front panel mounting hardware and rails.

Then, 200 - 175 = 25mm, spread equally at the top and bottom gives 12.5mm clearance.
