Lian Li Dan Cases A4-H2O PC tower case

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.

Features:

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:
- 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 Living Space:
- Minimalist black or silver design of the A4-H20 feels right at home in any living space. The small 11-liter volume is small enough to feel like it’s not even there.

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.
