Abstract: A compact disk storage box associated with a front panel of a computer case has top and bottom plates of the same configuration, two opposed side plates, and a back plate to constitute a box with an opening at the front. The side plates are equipped with a plurality of opposed rails on the internal surface to guide inserted compact disk trays. One of side plates is provided on the front edge with a vertical row of spaced end buttons each of which has a free end so that when a compact disk tray is pushed into the box, the tray urges inwardly a resilient ejector arranged on the back plate until it is caught by an end button. Users can move the end button sideways to release the tray for storage or retrieval of a compact disk. The box can be accommodated inside the lower portion of a computer case and combined with the case.

Abstract: The present invention discloses a compact disk storage tower structure that is associated with a front panel of a computer case to provide convenience in the retrieval of compact disks.

The housing has a wide open front, a plurality of curved ledges formed on the internal side walls, a pin hole located away from the ledges and extending from the top of the housing to the bottom, engaging openings well-balancedly provided on exterior walls thereof, and an upper and a lower groove integrally molded to serve as a receptacle for a speaker. The housing accommodates a plurality of compact disk trays each of which has a stepped flange with a holed protrusion on one side end and a thin flexible flat slab angularly extending from the peripheral surface.

Abstract: A compact disk storage compartment is mounted in a opening of a front panel of a computer case. The compartment exterior and front panel peripheral rims have engaging means.

Abstract: A video/audio medium rack at least including four connecting rods, four wall boards and a back board. The wall boards are disposed with tenons interlacedly engaged with engaging slots of the connecting rods so as to assemble the wall boards with the connecting rods. The back board is formed with peripheral stopper edge for fitting into channels of the wall boards so as to assemble the back board with the wall boards. CDs and VHS tapes can be both rested in the rack. Several racks can be stacked or assembled to enlarge the capacity of the rack. A base is disposed under the bottom of the rack and rotatably fitted with a bottom dish, whereby the base together with the rack can be rotated relative to the bottom dish.
