Silencio 450

Disclaimer: Displayed parts and accessories may not be included in the actual product package.


The Silencio Series represents the best solution for sound absorption with system builds of all levels. Sound silencing foam padding seeks to severely reduce system noises produced by hard drives, numerous cooling fans, and other devices. Combine this with a solid-steel frame, vibration inhibiting rubber feet, two Cooler Master quiet-spinning fans and the Silencio 450 nearly becomes completely silent. Those that value a quiet computing space will immensely appreciate the Silencio Series.
