Abstract: A casing includes a shell, at least one carrier tray, at least one slide rail assembly and a buffering component. The shell has an accommodating space and an opening corresponding to the accommodating space. The carrier tray is located in the accommodating space. The slide rail assembly includes an outer rail fixed to the shell, a middle rail, and an inner rail. The carrier tray is fixed to the inner rail, such that the carrier tray is slidably assembled with the shell through the slide rail assembly, thereby being extracted outward from the opening or entering the accommodating space through the opening. The buffering component is assembled with the shell, penetrates through the shell and the outer rail, and is pressed against the middle rail. When the middle rail slides relative to the outer rail, the slide rail assembly is buffered by the buffering component.

Abstract: An air ducting cover for guiding a directed flow of air output by rotation of a fan is proposed. The air ducting cover includes a frame for covering outside of the fan and a flexible cover member having a channel formed therethrough for connecting with the frame. By such arrangement, the directed flow of air output by the rotation of the fan can be guided flexibly by the means of the channel. The ducting cover is able to provide flexibility in common use without the need of being re-designed to meet different applications. Further, the flexible cover member can be replaced easily, so as to solve prior-art problems.

Abstract: A slide bearing supporting frame for supporting and mounting a slide bearing to a rack having locking holes, includes at least one locking part penetrating at least one of the locking holes and for being locked to the at least one of the locking holes of the rack via a fixer, for allowing the slide bearing frame to be fixed on a rack with locking holes of different sizes.

Abstract: A fixing device for fixing a heat sink in an electronic device is proposed. The fixing device includes a first fixing member and a second fixing member both for being mounted to the electronic device. The first fixing member and the second fixing member respectively further include a first fixing portion and a second fixing portion both for fixing two surfaces of the heat sink, and a first connecting portion and a second connecting portion, allowing the second connecting portion of the fixing device to be coupled to the first connecting portion of another fixing device mounted to another heat sink, so as to connect at least two heat sinks to each other. Therefore, the fixing device can be provided according to the number of required heat sinks, so as to eliminate prior-art drawbacks.

Abstract: A rack server is proposed that includes a rack case, at least a server, and at least an extended interface card. The rack case includes a front surface having a plurality of server slots for insertion of a plurality of servers, and a rear surface having a plurality of card slots corresponding to the server slots for insertion of a plurality of extended interface cards. The server is inserted into one of the server slots and has a rear end connected to a server connector. The extended interface card is inserted into one of the card slots and has a card connector for electrically connecting to the server connector of the server.
