I don't think you will find this with server hardware. I guess high end pc people secretly have some led-fetish as you don't see it with mid range hardware either. I must say I have some leds too and I like it, until I'm in bed and the whole room is a freaking colour show.. ha
That is cool and all, but shouldn't that be considered when purchasing the case? You can get your christmas lights on a cheap case vs a top of the line motherboard.
