Claim:
A server, comprising: a chassis, having a bottom plate, two side plates, a front end and a back end; a middle plate, disposed in the chassis, wherein the middle plate is perpendicular to the bottom plate and parallel to the side plates, and divides the chassis into a first sub-space and a second sub-space; a transfer plate, disposed in the first sub-space and adjacent to the back end; a main board module, disposed in the first sub-space, and suitable for being pulled out from the front end, wherein the main board module is electrically connected to the transfer plate; a hard disc module, disposed in the second sub-space, and suitable for being pulled out from the front end, and the hard disc module comprising: a hard disc cage, suitable for sliding into the second sub-space from the front end, wherein the hard disc cage has a first side and a second side parallel to the side plates, and the second side has a plurality of hard disc openings; a back plate, fixed to the first side of the hard disc cage and parallel to the middle plate; and a plurality of hard discs, detachablly disposed in the hard disc cage and electrically connected to the back plate, wherein when the hard disc cage is pulled out from the chassis, the hard discs are suitable for being installed to or pulled out from the hard disc cage through the hard disc openings; and a cable arranging module, comprising: a fixing frame, fixed on the middle plate; a chain structure, formed by a plurality of pivoted elements pivoted in sequence, wherein a first end of the chain structure is connected to the fixing frame, and a second end of the chain structure is connected to the hard disc cage, and the fixing frame and the chain structure commonly form a chamber; and a cable set, located in the chamber and electrically connected to the transfer plate and the back plate, wherein when the hard disc module is located in the chassis, the chain structure is bended and contained in the chassis, when the hard disc module is pulled out from the chassis, the chain structure drives the cable set to be curved and moved, when the hard disc module is pulled out from the chassis entirely, the chain structure is extended and at least partially located out of the chassis.
