If you've always wanted to add some illumination to your killer gaming rig, we can show you how. By far, this is arguably the easiest and safest way to do so. As always, you're doing this at your own risk. We aren't held responsible for anything that may happen to your property. Practice caution and safety at all times. Scroll down to step 1 to begin.
Steps
-
1Take out your Case's left side panel and clean it.
- Carefully unscrew the rear screws that hold your PC's side panel on to the main case.
- Slide it back and take it out.
- Assess the inside of the panel and see which parts you want to stick the LED strips on.
- Once you've chosen the part, get some tissue paper and wet it with alcohol.
- Rub the surfaces of the inside panel to remove dust, oil or any other substances that will prevent a great stick.
-
2Cut out the LED strips and secure them in place.
- Measure out and cut the strips to size. Most strips allow you to cut only every after 3 LEDs, so keep that in mind.
- Peel the back of the strips and lay them into the panel.

3Connect the strips in a parallel.
- Measure and cut the wire to connect the strips in a series. Add a little allowance, as you will have to use wire stripper to take the insulator off the ends of the wires.
- Using the soldering gun, connect the wires to the strips. Make sure that the diodes (+/ -) are correctly connected. Most wires are color coded so you are less likely to make the mistake of connecting the positive diodes to the negatives. White or Black is positive and whatever else color should be the negative.
- Use the hot glue to secure the wires to keep them from moving around in the case.
-
4Splice the LED strips into the MOLEX connector.
- The first end of the flexible LED strips should come with a pair of wires to connect power to. If not, then solder two wires to the positive and negative terminals.
- Grab your MOLEX connector. The Yellow wire is 12V, and the black is ground. Choose a connector you want to use as the place where you splice the connection. The connector end where the two branches meet is what you plug into the power supply.
- Use the wire stripper to split the black and yellow wire.
- Solder the black wire (ground) from your MOLEX connector to one wire from your strip assembly.
- Do the same for the other wire.
- Secure the connections by using some electrical tape.
-
5Plug in the MOLEX connector to a vacant male MOLEX connector from your power supply.
- Locate a vacant male connector from your power supply to connect to your strip assembly. When you power your computer on, it should light up.
-

QuestionOn the Molex female connector, what do I do with the red and relevant black ground wire?Community AnswerJust leave it if you don't mind, and also if you don't want the extra cables, you can always pull them out by squeezing the metal pins. If that is too hard for you, you can always cut them off.

QuestionI have four colored wires in my LED strip: yellow, green, blue and red. Which color do I connect to which?Community AnswerIt sounds like you have a multicolor RGB (red green blue) led strip. In that case, connect the yellow wire to the positive voltage line. If you connect the green wire to ground, the strip will glow green: the same goes for blue and red.
-
QuestionIs there any way to control the timing or movement of the lights?Community AnswerYou can using a micro-controller such as an Arduino or Raspberry Pi. You can use this in conjunction with an audio input from your PC and have the code configured accordingly.
