This article covers Fractal Design Define 7 XL ブラック つや消しアルミニウム.

Overview

The Fractal Design Define 7 XL is a full-tower PC case from Swedish manufacturer Fractal Design, featuring a brushed aluminum and steel exterior with a tempered glass side window. Its dual-layout interior allows you to choose between an open layout for maximum cooling and a storage layout that can hold up to 14 hard drives. Positioned at the high end of the full-tower market, this case is designed for enthusiasts who need extensive room for large motherboards, multiple GPUs, and custom water loops without sacrificing quiet operation.

Compatibility Guide

The Define 7 XL supports E-ATX (up to 285mm wide), ATX, mATX, Mini-ITX, as well as EE-ATX, SSI-CEB, and SSI-EEB form factors. The power supply mounts at the bottom and can accommodate long ATX units. Storage options are abundant: you can install up to 14 3.5-inch HDDs (in storage layout) plus 4 dedicated 2.5-inch SSD mounts, with an ODD bay that can be converted to an additional 140mm fan mount. The front I/O includes two USB 3.0 ports, two USB 2.0 ports, and one USB Type-C port.

Product Info

Released in late 2019, the Define 7 XL remains a top choice for silent builds. It comes with industrial-grade sound-dampening material on the front, top, and side panels. The top panel is interchangeable between a solid steel dampened cover and a ventilated filter-equipped panel, letting you prioritize silence or airflow. In the market, it competes in the high-end silent full-tower segment, appealing to users who need ultimate flexibility for storage and cooling.

Best Use Cases

Large-capacity storage server: Switch to the storage layout and fill up to 14 HDDs for a massive NAS or Plex server. The included brackets make installation tool-free and tidy. Custom water-cooling build: The case supports radiators up to 360mm in the front, 420mm in the top, and 280mm in the bottom, offering plenty of space for pumps and reservoirs. * High-performance silent workstation: With dampened panels and excellent airflow management, you can build a powerful rendering or simulation rig that runs quietly even under load.

Things to Consider

The Define 7 XL is a large case, measuring roughly 600mm deep, so ensure your desk or rack has enough depth. When installing a 420mm radiator in the top, check for clearance with tall RAM modules and motherboard VRM heatsinks – some combinations may require a low-profile setup. The case includes only two 140mm fans by default; additional fans or radiators will need to be purchased separately. Also, the solid front panel limits airflow if you don't use the ventilated top, so consider your cooling needs carefully.
