It makes a good night light if you've got a clear panel? (My mobo, for some reason, doesn't shut off the leds on the RAM when you put it to sleep.)
That's why I have lighting in my case. Instead of having a lamp turned on in my comp room, just have some lights in my case and have it act as the lamp. There's less eye strain, if the only thing lighting your room is the monitors. If you normally have your room lights turned on, then it's not a problem. I blacked out my windows and don't turn on the room light. I don't want it that bright, but I don't want it super dark either.
