My partner and I worked together to design and assemble my desk from T-slot aluminum extrusions. T-slot is amazing. It’s like Erector Set for adults, but nonproprietary and with more options. This allowed me to experiment and iterate and tweak things until the desk fit me perfectly. Aluminum extrusions make it super easy to mount virtually everything, from monitors to keyboards to cup holders. The shelves are finished plywood.
