I still feel that my PC case could do with a little more fluorescent lighting, or CFL tubes to be exact. I have one 12″ blue light on permanently, and another 12″ blue, combined with 2 6″ green tubes set to come on when the ambient noise triggers a sensor at a certain level. However, until I get a larger case, there is not much room to safely affix any more lighting. For lighting that is a little larger, such as you would use in a garage or home/office environment, check the link above.
