Fractal Design Define 7 Black Mini Tower Case


The Define 7 represents the pinnacle of Fractal Design’s esteemed Define series, setting a new standard for mid-tower cases in terms of modularity, flexibility, and user-friendliness. With its dual-layout interior, this case offers remarkable versatility and adaptability, allowing for ambitious builds and future expansion. The Define 7 incorporates industrial sound damping technology, ensuring a quiet computing experience while maintaining excellent thermal performance. Its classic clean styling adds a touch of elegance, making it an ideal choice for design-conscious PC builders. Whether you’re seeking a dependable case for your current build or planning for future upgrades, the Define 7 delivers the perfect blend of functionality and room to grow.


Fractal Design has taken a fresh approach with the Define 7, pushing the boundaries of innovation with its new dual layout design. Featuring a redesigned top and front panel, the Define 7 offers a sleek and modern aesthetic. The addition of tool-less push-to-lock top latching side panels makes accessing your components a breeze. With the new filtration system, you can keep your system clean and dust-free effortlessly.

One of the standout features of the Define 7 is its ability to switch between an open layout and a storage layout, giving you the flexibility to prioritize cooling or storage capacity according to your needs. This innovative design allows for greater airflow and improved cooling performance, as well as providing ample space for additional storage drives.

The Define 7 also boasts the ultra-slim Nexus 2+ fan hub, which enables you to connect up to three PWM fans and six 3-pin fans, allowing for precise control over your system’s cooling. Furthermore, the extensive cable management options along the edge of the case ensure a clean and organized build, keeping your cables neatly tucked away.

With its combination of versatility, enhanced cooling capabilities, and thoughtful design features, the Define 7 is a top-notch choice for PC enthusiasts looking for a case that offers both functionality and style.


The Define 7 introduces an impressive new top panel design that takes accessibility to a whole new level. By completely removing the top cover and cooling bracket, you gain unrestricted access to both sides of the motherboard from nearly any angle. This remarkable feature has been further enhanced with the introduction of an interchangeable top cover. Unlike previous generations, the new design eliminates any moving parts and plastic inserts, offering a more durable and user-friendly experience. The one-part steel covers are easy to install and provide a solid and sound-damped solution. In addition, the Define 7 includes a ventilated panel that can be effortlessly swapped with the solid cover, allowing for increased cooling support when needed. Whether you prefer a quieter setup or require additional airflow, the Define 7 gives you the flexibility to customize your case according to your specific requirements.


Equipped with three dynamic X2 140mm fans, the Define 7 Mid Tower ensures optimal airflow with two intake fans and one exhaust fan. With a total of nine fan positions available for 120mm or 140mm fans, you have numerous options for directing airflow within the case. For those who prefer water cooling, the Define 7 has you covered with extensive radiator support. You can install radiators up to 360mm in the front, 420mm in the top, and 280mm in the base (subject to the presence of an optical disk drive). The PSU shroud inlays in the case are removable and can be used as mounts for pumps, reservoirs, or drives using the included multi-bracket. Alternatively, you can remove them to create additional space at the front for accommodating large radiators. The Define 7 offers exceptional versatility to meet your cooling needs, whether you opt for air cooling or water cooling configurations.


The Define 7 takes the hassle out of PC maintenance, making it a fun, efficient, and simple task. It features high airflow nylon filters integrated on the front, top, and base of the case, providing full coverage for the power supply unit and offering front access for easy cleaning. Even if you decide to switch out the industrial sound damping steel top panel with the included ventilated panel, rest assured that it is also equipped with filters to minimize the entry of dust and other particles into your case. With the new chassis design that fully exposes the case interior when opened, there is no excuse for neglecting cleanliness in the Define 7. Keeping your system clean and dust-free has never been easier, ensuring optimal performance and longevity for your components.
