General information

Designed for Clean Interior Looks

Power supply shroud conceals drive cage and excess cabling, and ample space behind motherboard tray stows and organizes cables. Therefore all you get is a quiet and clean looking interior free of airflow obstructions.

General information

Optimized for Calmness and Serenity

Side and front panels are lined with industrial-grade sound dampening material to reduce annoying buzzing or whir. The top is pre-installed with ModuVent fan vent covers to block noise, which can be removed and replaced with optional dust filter if more fans are needed.

* For model with transparent window, the right side panel does not include noise damping lining.

General information

Robust Cooling Capability

The modernized internal layout of the Define C omits the optical drive bays, instead focusing on a clear straight airflow path. The open air designed interior creates an unobstructed airflow path from the front intake to the rear exhaust. Two preinstalled Fractal Design Dynamic X2 GP-12 120 mm fans (one front, one rear) deliver maximum airflow while still maintaining a low noise level. Easy-to-clean high airflow nylon filters are included on the front and base with full PSU coverage and front access for convenience. More fan mounts are provided for future cooling upgrade, including:

  • Front: 3 x 120mm or 2 x 140mm (1 x Dynamic X2 GP-12 included)
  • Top: 2 x 120/140mm
  • Rear: 1 x 120mm (1 x Dynamic X2 GP-12 included)
  • Bottom: 1 x 120mm
General information

Great Configurability

This compact form factor case supports ATX motherboard, graphics card up to 315mm in length, three 2.5” SSDs/HDDs on the back of the motherboard tray, two 3.5" HDDs at the bottom (under the PSU shroud), and features up to seven PCI slots. Thus you can build your power house for gaming or content creation without restriction.
