Cooler Master went back to the drawing table and improved the Silencio 550 as shown today with better cable routing, all black interior and an extra retaining hole. Obviously there are many ways to get the noise levels down with good cooling solutions and silent fans. But an overlooked part of the PC is the chassis itself.
With the side panels covered and very little airflow meshes to see the chassis still remains spacious enough for a mid-tower. You can house a good seven 3.5-inch hard disk drives inside, and a 2.5-inch tray will allow you to mount a SSD (solid state drive).
