Good catch. It seems bad. My only hope, here, is that the lost depth is due to some other need for the volume behind it, volume that is either accessible from the side of the cabinet, or volume lost to some need to accommodate something that has to be there (pipes, ducts, etc). If this is the case, then what could you display in such limited space bit books, pictures, or the like?

This reading seems pretty charitable, I know, but alleviates some of the infuriating for me.
