Abstract: A computer assembly comprising a computer housing and a plurality of separate outer casing members mountable in enveloping relationship with the housing; the plurality of outer casing members having an attached state in fixedly mounted relationship with the housing and a disengaged state in nontouching relationship with the housing; the plurality of outer casing members being toolessly switchable between the attached state and the disengaged state.

Abstract: A method of replacing a side panel member of a computer casing comprising positioning the computer with a bottom portion thereof exposed and pushing a push button on the bottom portion.

Abstract: This is a fancy yarn spinning device with the number of counts and twisting varying according to the variation of waveforms, designed with pre-defined waveforms, working with fixed cycles, fixed amplitudes, or random cycles, and random amplitudes, which serve as drafting and twisting parameters for the ring spinning machine. This device involves a servomotor and a inverter, for respective control of the revolutions of front, middle, and rear rollers of the ring spinning machine and the spindle, so the drafting rate and twisting of all areas of the ring spinning machine can change continuously with pre-defined settings, to produce yarns with variable number of counts and twisted conditions. The design of variable waveforms can also achieve different touch and visual feelings.

Abstract: A tower computer including a sheet metal housing having a plurality of separate bays housing a plurality of computer components, the plurality of separate bays including a first bay; and a power supply assembly readily removeably mounted in the first bay exclusive of any other of the plurality of computer components.

Abstract: A tower computer which includes a computer housing having a first bay with an access opening therein and a motherboard mounted in the bay opposite the access opening; a removable media drive mounted in the first bay which has a normal operating position in which access to at least a portion of the motherboard is blocked by the drive and a displaced position in which access is not blocked; the removable media drive being readily-displaceable between the normal operating position and the displaced position.

Abstract: A tower computer with a sheet metal housing which has a plurality of separate bays housing a plurality of computer components including a bay located at one vertical end of the sheet metal housing with a media drive assembly readily-removeably mounted therein exclusive of any other ones of the plurality of computer components.

Abstract: A computer comprising of at least one electrical connection port, an exterior casing overlying the port and having a casing opening in axial alignment with the port, a door member displaceable mounted on the computer, the door member having a plurality of translationally displaced operating positions comprising a first operating position with the door member positioned in the opening with an exterior surface thereof flush with a circumscribing surface of the exterior casing; a second operating position with the door member axially aligned with and inwardly displaced from the opening and a third operating position with the door member axially offset from the opening.

Abstract: A tower computer including a motherboard enclosure electrically shieldingly and physically enclosing a motherboard assembly mounted on a fixed wall portion of the enclosure; a panel having an open state and a closed state provided on the enclosure for enabling access to the motherboard assembly; and a computer component mounted in the enclosure in spaced relationship from the motherboard assembly and having a normal operating position in which it is located between the panel and the motherboard assembly in access interfering relationship with said motherboard assembly and a displaced operating position in access non-interfering relationship with the motherboard assembly, said computer component being readily-displaceable between the normal operating position and the displaced position when the panel means is in the open state.
