"The XClio 1000 Enclosure produces the largest light show of sorts I've ever seen on a prebuilt case. You have four choices in colors for each set of fans. There's red, green, blue, and chameleon where the fans change through various shades of purple, white, yellow, or what not. It practically out does my controllable lights on the Christmas tree. (No, you can't put this case on top of the Christmas tree...or can you?)"
