Enhance the style and storage of an entertainment center with stackable storage cubes. Assemble this unit by screwing together two 15-inch open cubes and one 30-inch cube with drawers. Sandwich the assembly between two 3/4-inch pieces of medium-density fiberboard (MDF) using screws. Align the pieces on the sides and back, leaving a 1/2-inch overhang on the front. Finish by fastening eight metal legs.
