Abstract: A heat-dissipating structure includes a support unit and a fan unit disposed in the receiving space. The support unit has a plane portion, a support portion extending downwards from a front side of the plane portion, and an opening passing through the plane portion. The plane portion has a board body, a concave space formed on the top surface of the plane portion, a non-skid pad detachably received in the concave space, a slender block body disposed on a base of the top surface of the board body, and a slender non-skid body disposed on a base of the bottom surface of the board body. The support portion has a support body, a receiving space formed in its inside, a plurality of slender openings formed on two opposite lateral sides of the support body, and a slender non-skid body disposed on a base of the support body.

Abstract: A media-storing fixed frame, a computer casing and a computer host are disclosed. The computer host includes a host frame, a media-storing reader, and an operation panel. The media-storing reader is fixed in the host frame, and the media-storing reader having a setting direction relative to the host frame is changeable. The operation panel is detachably fixed on an outside portion of the host frame, and the operation panel defines a referring direction that is changeable. When the computer host is vertical or horizontal, a setting direction of the media-storing reader and a setting direction of the operation panel are changeable according to user's operation habit.

Abstract: A panel structure includes a large door and a small door. The large door and the small door can be opened and closed. The opening direction of the small door is different from that of the large door. The small door is set in a place which has a plurality of installed openings for installing any type of CD-ROM drive or hard disk. Hence, a user can assemble, disassemble, or replace a CD-ROM drive or a hard disk by simply opening the small door and without opening the large door. Therefore, it is convenient for the user to assemble, disassemble, or replace a CD-ROM drive or a hard disk, insert something into an expanded port, or press any buttons.

Abstract: A folio shielding mechanism suitable for protecting an operation surface of a host is provided. The folio shielding mechanism includes a first shell, a second shell, and a transmission module. The transmission module is disposed on a first supporting surface of the host adjacent to the operation surface, and is connected to the first shell and the second shell. When the first shell is moving towards a first direction, the second shell is driven by the first shell through the transmission module and moving towards a second direction opposite to the first direction, so that the first shell and the second shell would be either joined together above the operation surface for covering the operation surface or apart from each other for exposing the operation surface.
