Lian Li DAN A4 H2O Black Mini ITX Tower Gaming Case

The Lian Li DAN A4 H2O Black Mini ITX Tower Gaming Case is an 11-liter small form factor case, a collaboration project with DAN Cases. Based on the original DAN A4-SFX case sandwich layout concept, the A4-H2O continues the minimalist and compact form factor. Furthermore, it comes with improved hardware compatibility, including support for AIO water cooling, and simplifies the installation process for a premium SFF build experience.
Compact Design & Enhanced Compatibility
This case masterfully blends a minimalist design with impressive hardware support. At only 11 liters, the A4-H2O is one of the smallest cases on the market that supports a triple-slot GPU and clearance for 240mm AIO water cooling. Specifically, its premium aluminum exterior with ventilation on most sides ensures components stay cool while maintaining a sleek look. Additionally, the sandwich layout design is key to its compact yet capable nature.

The sandwich layout allows a triple-slot GPU (up to 322mm) to fit neatly behind the Mini-ITX motherboard, connected via an included PCIe 4.0 riser cable. This leaves ample room for a 240mm radiator (up to 55mm total thickness with fans) at the top, facilitated by a removable bracket for easy installation. Moreover, the case supports SFX and SFX-L power supplies, and all panels (front, side, top, bottom) are fully removable for straightforward building and cable management.
