LIAN LI Industrial Co. Ltd., a leading manufacturer of chassis and PC accessories, announces a new small form factor case made in collaboration with DAN Cases, the A4-H2O. The 11-liter compact case can support a 240 AIO and a triple slot GPU up to 322mm long. With a minimalistic design featuring anodized and sandblasted aluminum panels, the A4-H20 is available in black and silver and is available with a PCIe 3.0 or 4.0 riser cable.

Designed by DAN Cases – Produced by LIAN LI

Based on the design of the A4-SFX, the A4-H2O keeps the same clean aesthetic and minimalistic concept but increases GPU size compatibility and AIO water cooling support. At only 11 liters, the A4-H2O truly encompasses the small form factor spirit with a clever new design by Daniel Hasen from DAN Cases, while being produced through the experienced manufacturing hands of LIAN LI.

All-around Removable Aluminum Panels

The steel frame of the A4-H20 is flanked with anodized and sandblasted aluminum panels, perforated at the top and side to provide direct airflow to all hardware. All the aluminum side panels are secured to the case with snap pins, making their removal quick and effortless. When removed, the front panel gives way to a wide opening to simplify the installation of large GPUs. At the bottom, a perforated aluminum panel can be removed to mount the SSD out of the case and provides access to the PSU for easier cable management

Compact and Powerful

The A4-H2O achieves its small footprint by organizing the hardware layout in a sandwich layout. The Mini-ITX motherboard tray and removable SFX or SFX-L PSU mounting bracket are located on the left side of the case, the right side offers enough room to vertically mount up to a triple slot and 322mm long GPU. At the top, a removable bracket can host up to 55mm thick radiator and fans of a 240 AIO with CPU block up to 55mm in height. A 1x 2.5” SSD mounting area featuring rubber grommets is located at the bottom of the case.

The A4-H20 is available for pre-order starting February 9th, 2022.
