Heres the final project http://www.instructables.com/id/ATX-Desktop-Computer-Power-Supply/ 

So I realize that after viewing multiple instructables and creating multiple projects I was using up batteries like crazy. I decided to wire up my own power supply after doing a quick search. My power is capable of your standard voltage of 3.3, 5, and 12. This setup and process that it took to create this project was about 2 hours including the package design. The Package design was simply made out of sheets of plastics I had lying around. It has a blue LED to indicate that it has been turn on, and a red and yellow LED to show the flow of power.
You can find 2 videos at the end of this project that shows me testing out the power box.

This was an important project to me because it allows me to save countless amounts of batteries in the never future, and this is Important to a kid like me going to college because money wont be easy to come by. Not only can you power possibly 3 devices with a little modification but you will end up creating a greener and more cleaner world. Sure its still using electricity but at least it is not using harmful batteries that are hard to get rid of.

Banana jacks
12V switch
300 ohm resistor
ATX connector (purchased or scavanged)
2 leds
Some type of enclosure
Electrical tape

1. First you bundle up the main wires which are Black, Red, Orange, Green, and Yellow. Gray and purple are used to create a stand by and power on light.
2. Then you solder on the green wire onto the negative terminal of the switch. Follow the diagram for the rest of the set up of soldering. I started off by soldering on the Resistors first and then the Leds. This is a easy but delicate process. Solder on the purple and grey wires if you want the stand by and power on lights. Unfortunately i forgot to take a picture of the me soldering on these wires.
3. Create a package or housing unit for your project and you plug up your power unit and your done.
