Lian Li DAN A4 H2O Black Mini ITX Tower Gaming Case

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.
