4 shelves at 2ft tall? 8" clearance for the 3 inside shelves... Does it need to be one piece of equipment wide? If not Walmart has a 40" wide 2' tall shelf that matches the 4' tall one previously mentioned for the same price. It's designed to hold up to a 42" TV, but I use mine for all my gear and put my center speaker on top under my Front Projection screen.
