Here is some food for thought:
If the computer is in your room, and on at night, some quiet, non led fans are AWESOME!!!! I wish that I didnt get led fans, because it lights up my room at night.
so if you use it at night in your room, and light is a factor, then get just normal fans.
but if its used at parties, and stuff where it needs to look cool, get led fans.
If you want lights, just get some Cold Cathode 12" tubes. blue is the brightest
