After awhile, the lighting inside the case will get to you--that is, if you're the type of person that leaves the PC on all night and it's in the same room where you sleep. I am in that predicament right now. It is nice though. You get to see how things are running inside the case. For example, I glance in every once in awhile to check on the fans to see if their spinning (CPU, system fans, etc). It's right there in front of your eyes without having to open up the case or turning on the flashlight.
