Lian Li A4 H2O (M-ITX) Cabinet (Black)
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.
The A4-H20 is smaller in size than most consoles, and the minimalist design suits any living space or any entertainment center to enjoy games or movies.
Minimalist Design – Black or Silver
A minimalist design, the A4-H2O has premium aluminum exterior with ventilation from almost most sides. The A4-H2O is available in black or silver.
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.
PCIe-3.0 and PCIe 4.0
The A4-H2O includes a PCIe Gen.3 or PCIe Gen. 4 riser cable, to vertically mount the GPU and place it behind the motherboard. The PCIe 4.0 riser cable supports transfer rate of 16GT/s (double the speed of PCIe 3.0). PCIe Gen.4 riser cables are backwards compatible with PCIe Gen 3.
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.
Triple-slot GPU Compatible
Removing the front panel provides a wide opening at the front to insert larger graphics card into the case with ease. The spacious interior supports a triple-slot graphics card of up to 322mm.
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.
Removable Bottom Panel – Cable Management & Storage
The removable bottom panel provides additional access to the inside of the case and makes for easier cable management. A 2.5” SSD drive can also be attached onto the bottom panel.
A 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. The A4-H2O is manufactured and sold by LIAN LI.
