Meshify strikes an aggressive pose in the Fractal Design lineup with unparalleled cooling performance and a defiant new look. Like black diamond facets, the angular asymmetry of the Meshify C carves a space uniquely its own as a new force in high-airflow design. Tempered glass with a distinctive tint completes the stealth-inspired black-on-black aesthetic with exceptional style.

An open ATX layout with intelligent space utilization creates an unrestricted airflow path from the mesh front intakes directly through key components to exhaust, ensuring heat is never an issue. The Meshify C has a remarkably compact footprint with the high-end component support of a larger tower, and with seven fan mounts and multi-radiator liquid cooling capability, it has the cooling capacity to match.

When performance is top priority and compromise is not an option, Meshify has you covered in style.

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.
