So far the desk is partially assembled with only 28, 8mm x 50 mm Domino's and their friction fit. I wanted to be sure that every thing lined up correctly before gluing the pieces together. I'll also be treating the edges and sanding a bit before the glue up. There will also be 2 upper shelves that will set on top of the desk. The picture of the CAD drawing and the attached PDF file will explain it all, so to speak.
