Abstract: A base-adjustable apparatus includes a main device, a base plate attached on the underside of the main device and a pivot shaft. The main device defines at least two holes therebottom. The base plate has a front section defining a through hole and a rear section formed with at least one bolt to be received in the respective hole of the main device. The pivot shaft is rotatably received in the through hole of the base plate and extends outside the underside of the base plate. Moreover, the pivot shaft has one end fixed on the underside of the main device and the other end blocked outside the through hole. The length of the pivot shaft extends to such an extent that the pivot shaft together with the main body is allowed to be lifted up to a predetermined height limit higher than the bolt and be rotated.

Abstract: An adjustable base for carrying a device movably comprises a base body having at least two supporting portions which are extending and protruding from the base body oppositely and respectively. Additionally, one supporting portion is exposed greater than the other supporting portion when the device is moved to a position away from the middle of the adjustable base.

Abstract: A cooling module for a computer system has a fan module, a heat sink module and an air wall. The heat sink module is connected to a circuit of the computer system for conducting heat generated by the circuit. The fan module makes air flow from an air inlet of the fan to the heat sink module where air absorbs heat generated by the circuit, and flow out from an air outlet of the heat sink module. The air wall is set between the air inlet of the fan and the air outlet of the heat sink module for isolating airflow from the air outlet of the heat sink module to the air inlet of the fan, such that heated air from the air outlet of the heat sink module will not significantly flow into the air inlet of the fan, and cooling efficient is therefore increased.

Abstract: A computer housing comprising a front panel, a receiving chamber, a door plate, and a main body provided with an inner space being allowable to accept an electronic device such as a floppy drive, CD-ROM, hard disk or the like that can be placed therein or removed therefrom. The front panel has at least one access port for access to the electronic device, and the receiving chamber is located within the inner space of the main body and is connected to the access port. The door panel is engaged with the front panel and moves between a first position covering the access port and a second position being retracted in the receiving chamber, and thereby exposing the electronic devices. When the door panel is retracted into the receiving chamber, the electronic devices can be easily accessed without the interference caused by the door panel.
