I'd like to replace the whining 80mm front fan in my microfly. At first I was thinking about putting in a 120mm, but that would require cutting supports and the 3.5" bay where I have a hard drive mounted. A 92mm will fit where the original 80mm is and all I have to do is cut the bigger hole. I know it will be quieter and move more air, but is it worth it? I could possibly fit 2 92mm fans in without cutting supports or drive bays as well.
