Fractal Design Define 7


Fractal Design’s Define 7 is the 2020 iteration of its highly successful Define series of traditional PC cases. It is available in several varieties, including a smaller ‘Compact’ and a larger ‘XL’ model, with or without tempered glass side panels. Three preinstalled fans (Fractal Design Dynamic X2 GP-14) are included fans are included with the case, and there is room for a total of up to nine fans.

Key Features

Highly modular design: You can remove the entire top of the case for easier building and cable routing. The default open layout can be converted to a storage layout with room for up to 14 hard drives, four SSDs, and one optical drive. All motherboards up to and including the E-ATX form factor are supported.

Preinstalled sound-dampening: The Define 7 is optimized for silent operation, as it includes industrial sound-damping material on the inside of the front, top, and side panels.

Comprehensive cooling options:  The case ships with three fans preinstalled, but there are mounting positions for up to nine 140 mm or 120 mm fans in total. Radiators up to 420 mm are supported. An optical drive bay can be converted to make room for an additional 140 mm fan in the front. High-airflow nylon filters are included to prevent dust buildup.

Despite its fairly compact size, especially in height, the Define 7 has support for large components , liquid cooling systems and really impressive support for a multitude of storage units.
