A systemic cabinet is composed of multiple boards 1 and multiple connecting pieces 4. Each board 1 has multiple mortises 11 defined at sides respectively to combine the corresponding connecting pieces 4 with supporting strength by wedging to perform configuration of the systemic cabinet. The connecting pieces 4 have multiple types in design variation to provide orientation-positioning efficiency and have supporting strength to make the composed systemic cabinet firm and stable. Therefore, once one board 1 is worn out, only the worn board 1 is replaced by detaching the connecting pieces 4 to save other elements and to make the replacement easy and environmental for future repair.
