LIAN LI A4H2O Mini-ITX Case Silver & Black With PCIe Riser 4.0

The A4-H2O 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 with improved hardware compatibility (including AIO water cooling) and simplifies installation.


11-Liter Form Factor

At only 11 liters the A4-H2O is one of the smallest cases on the market that supports triple-slot GPU and clearance for 240 AIO water cooling.

Sandwich Layout Design

The sandwich layout allows for a triple-slot GPU to fit into the compact size case. Matched with a PCIe Gen. 3 or Gen. 4 riser cable the GPU is located behind the motherboard and leaves room for a 240mm radiator at the top of the case. Bottom side and top mesh panels ensure that the components get cooled directly with fresh air intake.

Fully Removable Panels

Front side top and bottom panels can all be removed easily to provide easier access for installation and/or cable management.

IO and Power

Located on the left side of the case inside a recessed cutout the front IO includes a USB 3.1 Type-C (internal Key-A) port a Mic port an HD-Audio port and a USB 3.0 Type-A port (internal 19pin). At the top of the recess is a premium-grade power button.

Optimized airflow for 2 slots GPUs

The extra standoffs helps pushing a two slot GPU toward the side panel in order to exhaust or intake fresh air directly out of the chassis.
