Abstract: An improved prefabricated cabinet assembly characterized by first and second precut opposite end bulkheads and one or more precut intermediate bulkheads lying in spaced, mutually parallel planes and rigidly connectable to a plurality of precut front panels lying in a common plane normal to the planes of the bulkheads. Each intermediate bulkhead is provided with clip assembly means for mutual interconnection with a corresponding one of the front panels proximate one vertical edge thereof and adjacent the vertical edge of the next adjacent front panel. Each intermediate bulkhead further includes clip assembly means for rigidly connecting the intermediate bulkhead to the front panel next adjacent the front panel corresponding thereto. Also disclosed are upper and lower precut back supports which mutually interconnect the end bulkheads and intermediate bulkheads to complete the rigid cabinet assembly.
