Lian Li A4-H2O Overview

Save room on your desktop or entertainment center with the compact design of the Lian Li A4-H20 Aluminum Mini-ITX Computer Case. Designed for builders who want a full, robust experience in a smaller form-factor, the A4-H20 offers support for resource-hungry components without compromising performance.

Designed to leverage every inch of its aluminum and steel design, the A4-H20 supports Mini-ITX motherboards as well as SFX and SFX-L power supplies. Three expansion slots allow you to easily install graphics cards up to 12.6" in length and you get 2.1" of clearance for CPU coolers. While the A4-H20 sports a unique breathable design, you can install either two 120mm fans or a single 240mm radiator at the top of the chassis, enhancing airflow and balancing thermal performance. USB 3.2 Gen 1 Type-A and Type-C ports allow you to quickly connect your essential devices such as controllers and external drives. Dual 3.5mm audio jacks provide you with audio-out and microphone capabilities so you can communicate with others whether you are on a conference call or playing some of your favorite titles.

Minimalist Design
Anodized mesh panels and a solid front panel give the A4-H20 a modern minimalistic style without any of the extra bells and whistles, blending in seamlessly with your entertainment system or desk.
Sandwich Layout
Designed to squeeze out performance without compromising power or thermal dynamics, the A4-H20 uses a unique interior sandwich layout that fits your Mini-ITX motherboard, GPU, PSU, 2.5" SSD storage, and cooling solution with ease.
Fully Removable Panels
Install components easier with fully removable panels, giving you a clean 360° view of your internals. This enables you to easily route cables and adjust parts if needed. The removable bottom panel can house a single 2.5" SSD for easy storage management.
PCIe 4.0 Riser
A PCIe 4.0 x16 riser cable is included, supporting a vertically mounted GPU. It also supports PCIe 3.0 x16 through PCIe 4.0's integrated backwards compatibility.
Dan Cases Collaboration
The A4-H2O is an update to the popular DAN A4-SFX case with added water-cooling support. This is a special collaboration with Daniel Hansen from Dan Cases.
