A4-H2O
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.

A TRIBUTE TO SFF
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.

SIZE COMPARISION
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.

For Desktop
Small footprint of the A4-H20 fits on any desktop without taking up too much space for you to keep your space clean and spacious to game or work.

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.

Well Ventilated
Aside from the front panel, the top, sides and back of the A4-H2O are well ventilated with fine mesh which allows fresh air intake to enter the case.

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.
