11L Small Form Factor Design
A4-H2O uses a compact 11L form factor for space-saving Mini-ITX builds
It is smaller than many game consoles and fits well in compact desktop or entertainment setups
The silver aluminum exterior gives the case a clean minimalist look
Sandwich Layout
The sandwich layout places the graphics card behind the motherboard
This helps fit powerful hardware inside a compact chassis
The case supports triple-slot graphics cards up to 322mm long
Removing the front panel provides a wide opening for easier installation of larger graphics cards
PCIe 5.0 Riser Cable
A4-H2O includes a PCIe 5.0 riser cable for vertical GPU installation
The riser cable supports up to 32 GT/s
It is backward compatible with earlier PCIe generations
240mm Radiator Support
The top compartment supports a 240mm radiator
A removable top bracket helps make AIO installation easier
The radiator and fan combination can be up to 55mm thick
Fully Removable Panels
The front, side, top and bottom panels can be removed for easier installation and cable management
The top, side, bottom and rear panels use fine mesh ventilation
This allows fresh air to reach the internal components directly
PSU and Storage Support
The case supports SFX and SFX-L power supplies
A pre-routed power cord extension is included
The removable bottom panel can hold one 2.5" SSD
The removable bottom panel also gives additional access for cable management
I/O and Compatibility
The side I/O includes USB 3.0 Type-A, USB 3.1 Type-C, Mic and HD Audio ports
The case supports Mini-ITX motherboards
CPU cooler clearance is up to 55mm
