DD0KP Heiner, my layouts for the Pro version of Jean-Pierre F6DZP are already finished. There are two versions for vertical (see picture) and horizontal type of the Serit NIMs.
I know the board from BG0AUB. In contrast, I do not use SMD components, but only wired ones, which makes the replica much easier. The board fits into an inexpensive housing made of aluminum profile for standard cards (100x160 mm). Optionally, you can use a higher case when installing a display.
