      "The Silencio 550 chassis has a classy look with sleek lines throughout the chassis and a mirror finished front panel. The build quality is good and lives up to Cooler Master’s reputation. The sound deadening material on the doors does a very good job in keeping things quiet"

      "Being able to hold the GTX 590 in the default installation, without having to take out the removable hard drive cage, is a great feat for the Silencio. "

      "The Cooler Master Silencio 550 is imbued with most of the qualities required for a quiet chassis. The panels are solid, preventing noise from leeching out a side vent, the door masks the the hard drive(s) and intake fan noise, and the damping foam helps prevent standing waves. "

      "If you're in the market for an elegant, mature case without the bright lights big city look, and one that is sound insulated and functional, then this case might be for you. Sound insulation is this case's marketing point, although it does shine in other areas, such as cable management and build quality."
