Do you treat your computer like decoration or do you not care how it looks? Is it just a machine to you that serves a function or do you do things to it to make it look "cool" or personalize it a bit? I put colored fans and LED's in mine. Nothing really expensive. In fact, it's about the same price as the non lighted fans. I have red, and blue lights in it currently, and in some parts it appears to be purple due to the blended colors. It looks pretty cool with the lights off. I don't mind paying a bit extra to make it look nice.
