I have the 4 80mm fans on my sx1040b, along with a 120mm intake for the pci/agp, and one 92mm chimney up top. They are all panaflo's and run quite. I also did some led modding to it. I have an led hidden behind each grate up front, one on each side. they pan up and down in parellel like the nightrider lights, I also made a button below the reset button to turn them on/off. very slick case.
