Lian Li A4 H2O Black 4.0 – Mini-ITX PC Case / SFX, SFX-L / Aluminum panels / GPU 3 slots Tower

11 liter Form Factor
With a capacity of just 11 liters, the A4-H2O is one of the smallest cases on the market that supports triple-socket GPUs and has room for 240 AIO water cooling.

Size
A4-H20 is smaller in size than most consoles and its minimalist design fits in any living space or entertainment center to enjoy games or movies.

Minimalist design – Black or silver
With a minimalist design, the A4-H2O features a premium aluminum exterior with ventilation from almost every side. The A4-H2O is available in black or silver.

For Living Space
The A4-H20's minimalist black or silver design feels right at home in any space. The small volume of 11 liters is small enough to feel like it's not even there.

For Desktop
The A4-H20's small footprint fits into any workspace without taking up too much space, so you can keep your space clean and spacious to play or work.

Sandwich Layout Design
The sandwich layout allows for a three-socket GPU to fit into a compact case. Combined with a Riser Cable PCIe Gen. 4, the GPU sits behind the Motherboard and leaves room for a 240mm cooler at the top of the Case. The bottom, side and top meshes ensure that the components are cooled instantly by the intake of fresh air.

Easy AIO Installation
A removable top bracket makes it easy to install Radiators up to 240mm long. The upper space accommodates a Combo Radiator with a fan up to 55mm thick.

Supports SFX, SFX-L power supply
A removable mounting bracket is designed to support the SFX and SFX-L power supplies. An extension power cord is also included, which is pre-routed so as not to interfere with other hardware.

Fully removable panels
The front, side, top and bottom panels can be easily removed to provide easier access for installation and/or cable management.

Well ventilated
In addition to the front, the top, sides and back of the A4-H2O are well ventilated with fine mesh that allows fresh air to enter the case.

I/O and Power
On the left side of the Case inside a recess, the front IO includes a USB 3.1 Type-C port (internal Key-A), a microphone port, an HD-Audio port and a USB 3.0 Type-A port (internal 19pin).

PCIe 4.0
The A4-H2O includes a Riser Cable PCIe Gen. 4, for the vertical placement of the GPU and its placement behind the motherboard. The PCIe 4.0 riser cable supports a transfer rate of 16GT/s (twice the speed of PCIe 3.0). PCIe Gen.4 riser cables are backward compatible with PCIe Gen 3 cables.

Triple slot GPU compatibility
Removing the front panel provides a wide front opening for inserting a larger graphics card into the Case with ease. The spacious interior supports a triple-slot graphics card up to 322mm.

Optimized airflow for 2-socket GPU
The extra standoffs help push a dual-socket GPU toward the side panel so fresh air can be drawn in or out directly from the chassis.

Removable bottom panel – Cable management and storage
The removable bottom panel provides additional access to the interior of the case and facilitates cable management. A 2.5″ SSD drive can also be attached to the bottom panel.
