Just to build on what Tidal said about the similarity to a 19" rack. If your console/keyboard uses a trackpoint or trackpad then the room allotted might be ok (since you would not have a mouse), however unless the tray that holds the keyboard extends out further, you are not going to have a lot of leg room (ok for standing, not for sitting).
It is an interesting concept that isn't particularly well executed.
Yeah, I won't be sitting on it sice the boxes will be headless? I have a 17 inch flat panel to put inside and a keyboard and mouse. I have a small rack now that holds everything it just doesn't match the rest of the office decor. I leave it for now, I forgot I have a 2U APC that will have no place in that setup.
