Classique White Corner Wall Cabinet by Essential Home Furnishings
I have assembled 4 of these by myself. I have a square dining room and it's tiny and I need every available space for glass/plate storage, so I put one of these in each corner - just on top of the baseboard molding and several inches below the chair-rail. There is a lot of white woodwork in the room and these look great with it and hold more than you would think. The instructions are just drawings, but each part is CLEARLY marked (don't get your cam locks mixed up - there are 2 types) and it's pretty intuitive. I actually love these and recommend them highly.
