Correct, if you look at Danny's website it is not listed, but it is the N3 Tower but in bookshelf form. It is a little cheaper too, no floor spikes, call him or email him for exact cost. This is the sealed version yes, i only make the backs on these removable to help out the new people so they could more easily insert parts and No Rez. Let me know if I can answer any other questions. Once you are done, the back can be sealed with foam lining or a small bead of generic silicon caulk then screwed back on. You don't see the inset back at all from the front or 180 degrees left/right.
