Product Description

The Silencio is a silent case that makes no compromises in thermal performance. Sound dampening material surrounds the system build, rubber padding cushions all included fans, and a removable cover shields noise that escapes from the top panel. The Silencio S400 is available with either a tempered glass or a sound-dampened steel side panel.

For demanding systems, the top panel’s Sound Dampening Cover can be removed for increased ventilation. Paired with the front panel’s ventilation, directionally taking in air through the mesh, silence can be accomplished without sacrifice. The subtle ventilation takes in air from three sides of the sound-dampened front door, with the mesh filter aimed toward the bottom for an efficient intake of air.
