Abstract: A hard disk fixing rack, which is used to emplace and fix the hard disks used in a computer, is composed of a seat which is fixed in an interior of a computer casing, a rack body, and a plurality of elastic gliding members which are installed on the hard disk. An interior of the rack body is formed with a plurality or rails, such that after the hard disk is gliding on the aforementioned rails, it can be fixed into locking slots at tail ends of the rails.

Abstract: A power supply fixing device can effectively fix a power supply inside a computer case. One end of the power supply fixing device is movably assembled at a plate in the computer case, and a suppress surface is used to suppress the power supply. In addition, by hooking at the other end, which is formed at the fixing device, to the other plane of the computer case, and by moving an operating member of the fixing device to a packing position, the entire power supply can be fixed. The entire operation process is performed without an aid of a hand tool, and there is no need to use screws or screw holes, such that the power supply can be dismantled and assembled more conveniently.

Abstract: A bi-directional side emplacing computer casing includes a cage, two side boards, and an expansion rack. Openings of the expansion rack are facing toward a left side and a right side to the cage respectively, and its two side walls are provided with plural sets of symmetric sliding grooves extended inward from the openings at two sides. The symmetric sliding grooves are not interconnected, so as to provide for a sliding and an insertion of expansion equipment having roller screws. In addition, the two side boards are all provided with expansion holes corresponding to the expansion rack, such that the expansion equipment can be emplaced at any side of the computer casing to be in compliance with a requirement of an operator.

Abstract: A motherboard fixing device that is installed within a case of a computer host computer, and, after installing a motherboard to a retaining panel, enables rapid assembly of the entire integrated motherboard and retaining panel within the case or extraction and replacement of the motherboard. Moreover, the present invention effectively avoids inadvertent damage to the motherboard when installing within the small space of a case.

Abstract: A panel cover structure for a computer casing, which is used to be pivoted on a front of the computer casing, is composed of a base panel, and at least one piece of decoration panel which is assembled on a front of the base panel, such that a noise transmitting from an interior of the computer casing to the front can be greatly reduced and a perfect protection effect can be provided, after the panel cover is closed. In addition, the aforementioned decoration panel can be made by splicing a single piece or multiple pieces of panel body, so as to generate a decoration effect of plural kinds of variations.

Abstract: An extractable motherboard seat plate of a computer case including a motherboard seat plate disposed on a lateral side of a frame for installing a computer motherboard is characterized that the back side of the frame is disposed with a long opening and a guide channel is respectively and oppositely disposed on the upper and the lower lateral sides of the long opening; at least one or more than one resilient press plate is disposed inwardly on one side of the guide channel; the motherboard seat plate slides into the guide channel; a big-end screw inserts a through hole on the back plate to fasten the motherboard seat plate onto the frame. The application according to the abovementioned structure is capable of fast installing or dismounting the motherboard seat plate to convenience the maintenance of the motherboard.

Abstract: The subject invention relates to an improved mechanism of drawer type hard disc converter rack, particularly to one with convenient removal and easy insertion of a drawer hard disc. The technical approach adopted in the subject invention involves such that, when the accommodating box and the fixed seat are combined, the user need only push the round jut on the handle, which has been put in a constantly-open status, into the bottom of the G-groove, and turn down the handle, so the jutting point of the handle is inserted in the dented groove of the fixed seat. In this way, the reactionary force from the jut that is pushing on the closing block will push the accommodating box into the fixed seat, to combine the two connecting ports.
