The Silencio S400
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.

Sound Dampening Material – Sound dampening material minimizes noise from the pre-installed fans, the power supply, all steel panels, the steel front door, and all storage mounting points for 2.5” and 3.5” drives.

Tempered Glass or Sound-Dampened Steel – The Silencio S400 is available in two versions. Seamless tempered glass to show the system build or sound-dampened steel for optimal noise reduction.

Removable Sound Dampening Cover – The top cover can be removed for increased ventilation or kept in place to reduce noise.

Reversible, Steel Front Door – The sound-dampened, steel front door features a reversible mounting system that is capable of opening in two directions.

Versatile HDD Cage – The HDD cage can be shifted to the front for more PSU clearance, backwards for additional front radiator space, or completely removed if HDD storage is not required.

SD Card Reader – The I/O Panel features an SD Card Reader for rich connectivity.

Headset Jack – The single 4 pole headset jack features both audio and microphone capabilities simultaneously so that separate jacks are not needed.

Silencio Fans – Two Silencio FP 120mm PWM fans are pre-installed with rubber padding to reduce noise. To connect additional fans, one 4pin 1-to-3 splitter is included.
