Description
The darkFlash DLH21 redefines the vertical ITX landscape with a sleek, minimalist aesthetic that fits seamlessly into modern professional and gaming environments. Measuring 239 x 175 x 412mm, this chassis utilizes a vertical chimney design to minimize its footprint while providing ample room for a 320mm triple-slot graphics card. The integrated ARGB lighting at the base adds a subtle, customizable glow, ensuring your build maintains a sophisticated presence without overwhelming your workspace.
This product is for:
- SFF enthusiasts seeking a vertical footprint to maximize available desk real estate.
- Gamers requiring compatibility for full-sized 320mm GPUs in a compact, portable build.
- Content creators who prioritize high-speed data transfer via integrated USB Type-C connectivity.
- Performance users who need 240mm AIO liquid cooling support for high-TDP processors.
- First-time ITX builders looking for an accessible layout with tool-less magnetic quick-release panels.

Building in the DLH21 is streamlined by its tool-less magnetic top panel and easy-to-remove side panels that provide 360-degree access to the interior. The 0.8mm SPCC steel construction provides a rigid, premium feel that resists flexing, while the five-sided dust filters ensure long-term component cleanliness. Thermal management is handled effectively by the pre-installed 92mm exhaust fan and the ability to mount a 240mm radiator on the side panel, pulling fresh air directly across the motherboard and GPU components.
Compared to traditional sandwich-style ITX cases, the DLH21’s vertical orientation offers superior GPU length support of up to 320mm and better compatibility for standard SFX-L power supplies. While many ultra-compact cases limit cooling to low-profile air coolers under 70mm, the DLH21 accommodates 134mm air towers or 240mm liquid cooling, making it a more versatile choice for high-end hardware like the Intel Core i9 or Ryzen 9 series.
