Cold cathodes or LED lights?

[Wort]

Hey guys. I want to install some light inside my rig.
First, I'd ask you: what do you prefer? Cold cathodes or LED lights?

Also, I'd like to have some cool UV lights inside my PC case. I've heard cold cathodes are better for this purpose...do you know any brand that makes cool UV lights (actual black light, not those PINKY glowing "UV" lights)
