Abstract: A multifunctional computer desk includes a rear board, two lateral boards, a face board, two corner insertion blocks and a pivotable board. A vertical wire channel is formed on an inner rear edge of each lateral board, whereby wires of business machines are placed in the wire channels and extend along a transverse partitioning board and extend out from recesses of the rear board to connect with the business machines on the desk. A small vertical channel is formed beside the wire channel, whereby each end of the longitudinal partitioning board is inserted in the small vertical channel. A transverse insertion groove is formed on a lower edge of the longitudinal partitioning board. One side of the transverse partitioning board is inserted in the groove, while the other side thereof is fitted in a stepped channel of the rear board. Two insertion slots are formed on two sides of the rear board. The corner insertion blocks can be inserted therein and mounted on two corners of the rear board.
