Fractal Design Define One Dark Solid

The Fractal Design Define One Dark Solid PC case serves as the perfect foundation for building a desktop computer and protecting internal components from external damage. Its Midi Tower design accommodates eATX, ATX, mATX, and mITX motherboards. Solid steel panels without windows are complemented by side aluminium vents that help natural airflow around the installed components. The case features bitumen sound-damping layers applied to the front panel and both side panels. The closed front panel absorbs vibration and noise from the internal fans and coolers during heavy CPU and GPU loads. This system helps maintain a quiet working environment in the immediate vicinity of your PC.

Key features of the Fractal Design Define One Dark Solid PC case

Steel panels with a bitumen layer dampen noise and vibration
Three pre-installed 140mm Momentum fans ensure steady airflow
Integrated GPU support bracket keeps heavy graphics cards stable
Removable fan brackets simplify water cooling installation
Top panel features a fast 20Gb/s USB-C port
Rear straps and routing grommets help with power cable management

Interior space and cooling support

Inside the case are three pre-installed 140mm Momentum fans featuring liquid crystal polymer blades. You can further expand the cooling system by installing liquid cooling radiators up to 360mm at the front or up to 280mm under the top panel.

Component installation

Tool-free access to side panels and removable fan brackets simplify installation and subsequent hardware maintenance. The interior offers space for graphics cards up to 368mm in length and CPU coolers up to 171mm tall, while the stability of heavy graphics cards is secured by an integrated support bracket alongside an air duct for more efficient GPU cooling.

Cable management and connectivity

The back of the motherboard tray features dedicated routing channels, straps, and grommets for neat cable management. The case also supports modern back-connect motherboards, helping to keep the interior clean and free of dangling cables. The top panel offers one fast 20Gb/s USB-C port and two 5Gb/s USB-A ports for data transfer and connecting external drives. Connectivity is rounded off by a combined 3.5mm audio jack for your headphones and microphone.
