Fractal Design Define 7 XL Black Midi Tower Case

Fractal Design Define 7 XL Midi Tower | Full Tower E-ATX Chassis

The Fractal Design Define 7 XL Midi Tower Black is engineered for professionals requiring extensive hardware capacity. This full-tower case supports motherboards up to SSI-EEB and offers a dual-layout interior. It suits UK users building high-end workstations or silent servers. The chassis prioritises modularity, allowing you to configure storage or cooling exactly as needed.

Technical Overview & Dimensions

This chassis offers a volume of 77.6 L with a steel construction and tempered glass side window. It measures 566 mm in height and 604 mm in depth. The design emphasises silent operation with sound-damped panels. It does not include a power supply, so you must select a compatible ATX unit.

Dual-Layout Interior & Motherboard Support

The Define 7 XL features a spacious dual-layout interior. You can switch between storage-optimised and open layouts for maximum cooling headroom. It accommodates large motherboards, including E-ATX and SSI-EEB formats. This flexibility ensures compatibility with enterprise-grade hardware. The internal width is 240 mm, providing ample room for cable routing behind the motherboard tray.

Optimised Storage & Cable Management

This case supports extensive storage arrays. You can mount up to 18 HDD/SSDs using the included trays and brackets. The design incorporates a detachable PSU cable shield and Velcro straps. This simplifies cable management behind the board. A ventilated PSU shroud with a removable cover keeps the lower chamber tidy. However, the exact number of included drive trays is not listed here in our records; verify the box contents upon arrival.

Advanced Airflow & Cooling Capacity

Cooling performance is a key focus. The case supports radiators up to 480 mm in the front and top. It also supports a 280 mm radiator in the base. There are nine mounts for 140 mm fans or eleven for 120 mm fans. The chassis includes three pre-installed Dynamic X2 GP-14 fans. High-airflow nylon filters cover all intakes. These are easy to clean and protect against dust.

Silent Construction & Front I/O

Industrial sound-damped panels line the front, top, and sides. This ensures exceptionally quiet operation even under load. The top panel features a Moduvent cover, which you can swap for a filtered ventilation sheet. For connectivity, the front I/O includes one USB 3.2 Gen 2 Type-C port. It also has two USB 3.2 Gen 1 Type-A ports and standard audio jacks. Note that illumination is not included; the case focuses on acoustic performance.
