Here is a unit that in fact has a 51 1/2"cabinet. The piece on the right where the TV sits. Behind the doors on the left is the stereo equipment, the doors below the TV are for cd, dvd and video storage. The unit is made from maple with a natural finish and features custom crown and base mouldings.
This corner desk extends about five feet in either direction. Made from pine, it's gorgeous and currently for sale.
