Abstract: A pipe connector structure includes a base, having a through hole and a revealed upper surface, comprising a first thread portion for connecting to an intercommunicating device and a second thread portion located on the first thread portion; a lid, having a central through hole; a sleeve, accommodated in the lid; and a first O-ring, disposed at the revealed upper surface and encircling the through hole. The lid includes an inner thread structure corresponding to a thread of an outer sidewall of the second thread portion. Accordingly, a user is capable of accurately cutting a water cooling pipe having an appropriate length according to the revealed upper surface of the pipe connector structure, thereby effectively solving issues of being uncertain whether the water cooling pipe is completely inserted into the base and being likely inserted in an unaligned manner as well as reducing risks of liquid leakage.

Abstract: A control signal switching system generates a light emitting module control signal for controlling a light emitting module, and the control signal switching system has a switching module and a transmission module. The switching module receives a switching control signal, a first control signal and a second control signal and output one control signal selected from the first control signal and the second control signal according to the switching control signal. The transmission module is connected to the switching module for receiving the one control signal selected from the first control signal and the second control signal and generates the light emitting module control signal for transmitting to the light emitting module. Therefore, the light emitting module is in operation according to the light emitting module control signal.

Abstract: A computer case has a box having a back board with an opening; and a graphics card fixing board having a plurality of graphics card shields, wherein the graphics card fixing board corresponds in position to the opening of the back board and thereby is unfastenably attached to the back board of the box either longitudinally or transversely, allowing the graphics card shields to be lengthwise parallel to a height of the box whenever the graphics card fixing board is attached to the back board of the box longitudinally, and allowing the graphics card shields to be lengthwise perpendicular to the height of the box whenever the graphics card fixing board is attached to the back board of the box transversely. Therefore, a graphics card is selectively mounted in place, lying or upright, in the computer case.
