Abstract: A server adapted to a server rack. The server rack has a first and a second connectors at a rear end of the server rack. The server comprises a tray, a motherboard, an expansion board, an adaption board, a system board, a docking module and a first cable. The motherboard comprises a central processing unit. The motherboard, the expansion, the adaption board and the system board are disposed on the tray. The docking module comprises a third and a fourth connectors. The fourth connector is configured for electrically connected to the first connector, and the third connector is configured for electrically connected to the second connector. One end of the first cable is connected to one end of the third connector, and the other end of the first cable is connected to the adaption board. The first cable is electrically connected to the third connector and the adaption board.

Abstract: A server adapted to server cabinet having a fan assembly and a power supply. The server includes a chassis, a main board module, a data storage, a signal-transferring module and a docking module. The chassis has a bottom plate, a first side plate and a second side plate disposed on the bottom plate. The main board module is placed along the first side plate. The data storage module is placed along the second side plate. The signal-transferring module is placed along the first side plate. The signal-transferring module is located at the back of the main board module. The signal-transferring module is connected between the main board module and the data storage module. The docking module is disposed on the bottom plate. The docking module is connected to the data storage module and the signal-transferring module. The docking module is connectable to the power supply and the fan assembly.

Abstract: A calculating apparatus includes a baseplate, a first mother board module and a connection module. The baseplate includes a bottom surface having a first component layout region, a second component layout region and a connection component layout region all arranged in order from a first side to a second side of the bottom surface. The first mother board is drawably disposed at the first component layout region of the bottom surface. The first mother board includes a first tray, a first control board, and a first electronic hard disk drive. The connection module is electrically connected to the first mother board module so that the first mother board module is capable of performing external communication through the connection module.

Abstract: A server includes a storage module, a processing module, a motherboard and a fixing assembly. The fixing assembly includes a carrier, a stopper, a tray, a first locking part and a second locking part. The stopper is securely located on the carrier. The storage module is securely located on the tray. A bottom wall of the tray has a fixing hole. The stopper engages with the tray through the fixing hole to make the tray securely attached to the carrier when the tray is located at the second position. The stopper is removed from the tray when the tray is located at the first position. The tray moves between the first position and the second position when the first locking part is located at the first state. The first locking part cooperates with the second locking part to lock the tray at the second position.
