Are there any color changing lights for commputer cases on the market?

I don't know how to program and don't really want to deal with that I thought there might be a system that lets you plug differnt LEDs in it and it would change color but I haven't been able to find any.

There was a case I saw in a local computer shop that had like a lava lamp on each side, built into it, which did change colour. I think it was programmed in the case, but im not sure.
Did you try a search on Google?

A quick search on Ebay's Buy it Now turned up some of these 'slow color change LEDs' for $0.26 each, including shipping.
