CASEMOD: How to add custom LEDs to case (DIY wiring)

Specs: Windows 7 Ultimate x64, i7 3770K / Patriot Viper 1866 16GB
I want to buy bulk [ideally multicolor] LEDs, and wire them up cleanly in my case.

I've never worked with LEDs, but I'm very technologically savvy and it can't be that hard for a person of intelligence and technological know-how to be able to do.

Basically, I want to buy bulk LEDs and wire them up in my case, and I'd like to be able to [ideally] software-control the color, if possible; or whatever way to change the color is cheapest.

Don't want to spend more than $20 total on this mod, and don't want to make the inside of my case ugly with hot glue or wires all over the place. If need be, I'll be happy enough with one solid color I can turn off with just a switch. If I can do this project for only $5 total, I will be even happier!

This is more for fun than anything, as well as learning about LEDs because I always thought LEDs are cool. I already spend over $2000 on this new PC build, so I'm not looking to throw much more of my hard-earned money into it.

Simplest would be just to replace a case fan with one that includes LED(s).

Color control would not be very easy, especially via software without a special hardware controller and driver (but that wouldn't be DIY then).

Your basic power supply aux. connector (Molex) contains different voltages. Purchase or adapt a Molex connector from a non-usable device. Look up what these different available voltages are and make sure that you choose your LED(s) that are suitable or you will need to adapt it with suitable resistor(s) and wire in a small toggle switch.

If you are smart, you will test the set up from a different power source first, then retest it with the motherboard connectors and hard drives unplugged for the protection of sensitive equipment. Be sure that all connections are soldered, everything is insulated with heat shrink tubing (not electrical tape), and every component and wire is mounted and secured neatly and out of the way.

You have to be a little bit crazy to keep you from going insane.

I'm not looking for "simplest". I want the experience and knowledge of doing this myself.

Please give different answer.

Good suggestion though about cutting an unused molex adapter to use as power source.

p.s. I have a case which has the back part where I can hide wires.

So, you spent $2000 on a new build and you want to upgrade your case with a $20 budget? I know nothing about LED case lighting. I do know how to use Google though and that is what I would do.

No, I do not want to upgrade my case. I want to learn about LEDs and seeing how inexpensive LEDs are, combined with their utter uselessness in practicality, I do not want to invest any significant amount of money in them, as it would be a complete waste. If I spent money on every little thing, quickly it would be several thousands of dollars. This is called being wise with money spending.

If you were "wise with money spending", you wouldn't even consider something that's "utter(ly) uselessness in practicality". How about this, buy a string of xmas lights & wrap them around the case. Here's some nice ones:

Upgrading your case includes modding the case, which is what you asked about. lDid you even bother to click on the link?

If you want to learn about LED's wiring start with the basics:

Note that there are dual color LED's (3 pin, one shared).

There is stacks about LED's and their circuitry in Google to help you along.

Always pop back and let us know the outcome - thanks
