Lian-Li A4-H2O X4 Computer Case Mini-ITX 240 AIO cooling Anodized Black Exterior

Marketing Information

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.

Easy AIO Installation

A removable bracket at the top makes the installation of radiators up to 240mm in length much easier. The top compartment accommodates a fan radiator combo of up to 55mm in thickness.

Supports SFX, SFX-L Power Supply

A removable mounting bracket is designed to support SFX and SFX-L power supplies. A power cord extension is also included and pre-routed to avoid interfering with other hardware.

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.
