A systemic cabinet is composed of multiple boards and multiple connecting pieces. Each board has multiple mortises defined at sides respectively to combine the corresponding connecting pieces with supporting strength by wedging to perform configuration of the systemic cabinet. The connecting pieces 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 is worn out, only the worn board is replaced by detaching the connecting pieces to save other elements and to make the replacement easy and environmental for future repair.
