Finally, everything in one place.  This unit holds all my DVDs and CDs.  I had numerous solid oak wall units in various home locations.  A custom build would be the only other answer, and would ten times as much.  Fit, form and function makes the storage tower a very good deal.  It got a four (not 5) in that I didn't expect a cardboard back.  My unit backs to a stair railing and the back shows, other than that it would be a "5".
