Actually if you know what you are doing, you can make black lights look awesome in your case. I am going to be going with a black light because I only want certain things to glow, and with a black light you can control what you want to glow, to a certain extent. While with neon lights... like ericd said it illuminates the whole case which imho is just boring. i.e. with a black light you can make your fans glow if you paint them, cables with spiral wrap, and whatever else you want if you have the right materials. Also with a black light since not everything is glowing, it would even be more awesome complimented with EL cable. That's why I think black lights are better than neon, if you know what you are doing.
