I don't like CCFLs because they need extremely high voltages to work and don't last, and i don't find that comforting. I prefer LEDs because they:
1)use less power
2)last longer (50-100K hrs)
3)offer richer/vibrant colours
I have two Enermax TB Vegas Trio fans in my system, one in the front, and one in the back. When my computer is under heavy strain, for example, while my brother is playing Skyrim on it, it glows like a make-shift disco light in the dark.
