PC Spotlight: Light Off, Spot On
In addition to fan and light sticks, spotlights are a good means for placing a light source in or on cases, and come in single or multiple colors. The Taiwanese manufacturer Sunbeam even goes one step further, connecting tri-color LEDs with a controller called the Chameleon that installs into a free 5.25" bay. A dimmer knob adjusts the red, blue, and green colors of the four attached spotlights. The colors can also be turned off individually, allowing colors such as purple (by combining only red and blue.) The controller is set up for four light sources; for anything beyond that you have to install another Chameleon. The controller does not work with normal spotlights however.
