Abstract: A computer enclosure includes a cage with a pair of brackets fixed therein for rotatably supporting a mother board tray to which a mother board is fixed. The cage includes a front panel, a rear panel, a top panel and a bottom panel forming a receiving space for receiving the mother board tray. The brackets support shafts that are rotatably received in bores defined in the mother board tray allowing the mother board to be mounted to and/or removed from the mother board tray at a position outside the cage thereby reducing the size of the cage and thus facilitating miniaturization of the computer enclosure.

Abstract: Disclosed is an electrically-operated ornament travelling on a rail capable of explaining the free quadrants described in the Mobius Theorem. The ornament mainly includes a three-dimensional endless rail supported on a set of supports. The rail includes at least a twisted and turned part and a non-twisted part. Two parallel metal wires extend through a full length of the rail on both surfaces thereof. A controller is used to supply current to the metal wires and to control the magnitude and flowing direction of the supplied current. A moving body having rollers made of permanent magnetic material is magnetically attached to the metal wires. A transmission mechanism in the moving body is powered through the controller to drive the moving body to travel, back, or stop on the endless rail.
