Versatile Dual-Layout Interior

This chassis features a unique adaptable interior. You can remove the top panel entirely to build with zero hindrance or swap to the ventilated panel to gain three filtered fan positions.It supports large motherboards up to 285 mm wide (E-ATX). This flexibility ensures the case adapts to your specific build requirements rather than forcing a compromise on component choice.

Superior Cooling Capacity

The Define 7 supports extensive liquid cooling setups. You can install radiators up to 360 mm in the front, 420 mm in the top, and 280 mm at the bottom.The case accommodates a total of nine fans. It comes with three pre-installed Dynamic X2 GP-14 fans, providing strong airflow out of the box. High airflow nylon filters are included to keep dust out while maintaining easy access for cleaning.

The chassis includes six universal HDD/SSD brackets and two dedicated SSD brackets.A versatile Multibracket is also included. This allows you to convert any unused fan position into a drive or pump mount. The HDD cage features vibration-damped trays to reduce noise during operation.

Connectivity and Noise Dampening

The front I/O panel includes a USB 3.1 Gen 2 Type-C port (10Gbps), two USB 3.0 ports, and two USB 2.0 ports. The top panel is industrial sound-damped, ensuring quiet operation even with high-performance hardware.
