Modular mid-tower for versatile builds

The Fractal Design Define 7 is a steel ATX mid-tower that supports motherboards up to 285 mm E-ATX. Its dual-layout interior lets you switch between an open configuration for water-cooling and a storage-focused arrangement. Three Dynamic X2 GP-14 140 mm fans are included, and the top panel swaps between sound-dampened steel and a filtered ventilation cover.

Suits builders who need capacity and quiet

This case fits users planning custom loops with radiators up to 420 mm or large air coolers, and those who want room for many drives. The solid panels and high-density damping keep noise low. It is less suited for anyone who wants a tempered-glass side window or integrated RGB lighting, because neither is present.

Handles fourteen 3.5" drives and big radiators

In Storage Layout the chassis accepts up to 14 x 3.5" HDDs plus 4 x 2.5" SSDs using the included trays and brackets. The Open Layout clears space for radiators up to 420 mm and large reservoirs. Front I/O provides one USB 3.2 Gen 2x2 Type-C, two USB 3.0, two USB 2.0 and audio jacks.

Questions about this item

What motherboard form factors does the FD-C-DEF7A-01 support?

The case fits ATX, E-ATX up to 285 mm, Micro ATX and Mini ITX boards.

Will my existing 140 mm fans line up with the pre-installed Dynamic X2 GP-14 units?

Yes, all nine fan positions accept 120 mm or 140 mm fans, so your current 140 mm fans mount directly.

How can I verify the front USB 3.2 Gen 2x2 Type-C port is active after building?

Connect a compatible device and confirm the operating system reports a 20 Gb/s SuperSpeed USB connection.
