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.

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.

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.

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.

Front, side, top and bottom panels can all be removed easily to provide easier access for installation and/or cable management.

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.

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.
