A computer device includes a chassis, a rail disposed in the chassis, an electronic module slidably disposed on the rail, a cable set connected to the electronic device and a cable arranging module. The cable arranging module includes a fixed frame and a flexible frame. The fixed frame extends along a first axis parallel to and under the rail. The flexible frame is connected between the fixed frame and the electronic module. The cable set is located in the fixed frame and the flexible frame. When the electronic module is located in the chassis, a part of the flexible frame is supported on the rail and located on a second axis parallel to the first axis. When the electronic module slides out from the chassis, the flexible frame supported on the rail moves away from the rail along the second axis and at least partially moves to the first axis.
