So you've seen those LED fans for desktop computers, well I decided to put an LED in my MSI Winds fan as a cool looking mod. I used a RGB LED so that I could make it different colours. Basically I took +5V from the back of one of the USB ports (It doesn't affect it I can still plug devices into it and it runs). Then each colour had its own switch on a DIP switch so that I can turn each one on and off to mix the colours. I mounted the DIP switch underneath the case by cutting a hole in the bottom and gluing the switch in place. The LED is glued in the fan housing where it doesn't get in the way of the actual blades.
