How about just getting some bookcase units from Target, Office Depot, Ikea, or somplace like that and arrange them so they face out in the size you want. You could keep the top from sliding with little rubber feet, glue, caulk, or epoxy. Closet Maid (at Target and Lowe's) has those units that take square cloth bins where you could hide some of your goodies. They often go on sale, too.
