You don't realize how much media you have until you get new furniture and find out that it all won't fit!! Ended up leaving a lot of cds, dvds and VCR tapes(don't laugh) in boxes until I found this tower!!! There were many sizes but I decided to go with the biggest, so I would have room to grow.  Can't believe that I filled this thing up!! The fact that it revolves allows it to have a relatively small foot print which I really like.  I have cds, dvds, vcr tapes and videogames/blurays each have their own sides which works great, with room to grow(except vcr tapes LOL!!).  It turns pretty smoothly and is very solid.  Highly recommend!!
