PC case Fractal Design Define 7 Nano Black — Mini-ITX/Mini-DTX, ATX PSU, tempered glass, 205×399×361 mm

Fractal Design Define 7 Nano Black is a compact PC case designed for Mini-ITX and Mini-DTX builds. The open interior layout and bridgeless PCI expansion slots provide a direct airflow path from front intake to rear exhaust, while the case supports multiple 2.5" and 3.5" drives and accepts ATX power supplies. Front I/O includes five USB ports with one USB Type-C supporting fast charging and up to 10 Gbps data transfer.

Advantages

The case offers superior airflow through an open interior layout and guided airflow via a two-part modular air duct that increases GPU cooling efficiency. Bridgeless PCI slots ensure unobstructed GPU exhaust. A removable top bracket fully exposes the interior for easier installation and cable routing, and multiple front USB ports including a Type-C port provide convenient connectivity and fast data speeds.

How to use

Install a Mini-ITX or Mini-DTX motherboard and an ATX power supply, mount drives into the available 2.5" and 3.5" bays, and position GPU and cooling according to the case layout. Use the removable top bracket to fully access the interior for component installation and routing cables. Configure front fans and any additional fans according to the two-part air duct orientation to optimise airflow from the front intake to the rear exhaust.

Recommendations

For best thermal performance, install a 140 mm front fan and ensure the modular air duct is positioned to channel air directly over the GPU. Use the Type-C front port for high-speed peripherals and charging.
