We used upper cabinets to make a unit in our dining area. We stacked three upper cabinets on top of each other. The cabinets are of different height and the middle one has glass panels. We use the middle ones as a china cabinet and the top and bottom ones as storage. We used a 1x2 on the floor to give the cabinet some clearance for opening. We've had many compliments on the unit and people think it is a custom cabinet.
