A full line of shelving and cabinets may be assembled to the panels with a limited number of interchangeable components. The cabinets include a flipper door which will not rack when opened or closed, and which slides beneath the top of the cabinet in the open position, yet has its edges flush with the top and bottom of the cabinet in the closed position.
