A multi-purpose groove is mounted on the upper end of the front portion of the chassis body. A multi-purpose groove is provided with a data line card hole. A data socket is arranged in a middle portion of the front end of the host body. A left end column is installed at an upper end of the upper end of host body. A right end column is arranged on the right side of the left end column, and a handle is connected to the outside of the right end column. A handle groove is arranged at both ends of the handle, and a left end column is connected inside the handle groove; the host body comprises a host inner casing, a top sound absorbing panel and two side sound absorbing panels. The top muffler board is arranged on the upper surface of the inner casing, and the two side muffler plates are symmetrically mounted on both sides of the inner casing; a silencing sponge is arranged between the lower surface of the top muffler plate and the upper surface of the host body.
