For those that just LOVE fan bling, Enermax's APOLLISH VEGAS (what?) series is for you. Each fan has 15 LED points and is completely customizable to increase or decrease that number. The end result is a spiral of sorts and it looks pretty sharp. No idea on price, but the specs are in line with regular desktop fans (these are not high-performance).
