The Fractal Design Define One Dark TG Light Tint is a mid-tower PC case for builders putting together a gaming, creative or everyday desktop. Its support for a range of motherboard sizes and room for long graphics cards make it suitable for flexible system builds.

A closed front and sound-dampening front and side panels help reduce noise, while aluminium side intake vents and three pre-installed Momentum 14 fans provide airflow. The left side panel is tempered glass, so you can view the build, and tool-less access helps make installation and maintenance more straightforward.
