Cooler Master Sileo 500 is a mid-tower case with aluminum front panel designed to provide a very quiet computer. It has several noise-absorbing pads in its interior and its two 120-mm fans rotate at a very low speed (800 rpm) and thus producing almost no noise. You have also the option to buy this case with a Cooler Master eXtreme Power Plus 500 W power supply already installed. Let's see what you should expect from this case.
