That design is similar to the "Corner Cockpit" marketed by O'Sulllivan Industries as a computer desk & hutch combo several years ago. I teamed that up with a few of their matching file cabinets to make a very workable operating desk/work surface. As already suggested by others, some holes for cables, as well as a grounding buss on the backside, were a necessity. And yes, it sat away from the wall for easy access, even though the room was the smallest in our house.
Regrettably, that set-up went out the door as we downsized before moving out of SoCal. Glad to see a link to those plans in the OP; bookmarked it already. 73
