Are there PC cases that have light kits that flash to music?

[Chris G]

I am wondering if there are any computer cases out there made that have light kits that respond (flash or blink) to the beat of music. Preferrably a clear acrylic type case but doesn't have to be. If so, where could I find such a case? If there are no cases that come with that type of light kit already installed... are there kits that can be purchased to install in cases that will do that kind of lighting effects? Thanks
