You know the button on the top left(small square one) turns the front LED off right >_>
I have 2 200mm LED's and I like it. Also keeps things cool when you count the front 200mm red the side 200mm red and the top 200mm(no LED).
Mine is right next to me and the only thing I hear is my GPU fan when I fire it up. but other than that it's a nearly silent hum.
Yup, I usually leave it off tbh. My loudest fan at the moment is the one that is on the CPU heatsink. My friend has one he is going to give me that apparently has a temperature display on the fan and he says it runs super quiet.
O_O and holy poopcakes does this thing ever boot up fast. I was getting used to having time to go make a cup of coffee with my old PC lol.
(My cables are a mess atm, once I get them cleaned up I'll take some pictures... althought APPARENTLY I need to change my desktop background -_-)
