OCIA checks out the Tweakmonster Rev. 3 Lightstrip Kit in their latest review! Here's a snip.

As you can see, the lightstrip gives off a nice purple haze. Keep in mind that the light given off by the strip is not near as bright as a cold cathode. The goal of the lightstrip is not to flood the area with light, but to give individual components a nice glowing accent. Users can simply place the strip inside of their PC to help illuminate hardware... or you can choose to make a project of it.
