PCIe 4.0:

The A4-H2O includes a PCIe Gen. 4 Riser Cable for vertical GPU mounting.

Triple-Slot GPU Compatibility:

Removing the front panel provides a wide opening at the front for inserting a larger graphics card into the case.

Optimized Airflow for Dual-Slot GPU:

Additional standoffs help push a dual-slot GPU towards the side panel.

Removable Bottom Panel - Cable Management and Storage:

The removable bottom panel provides additional access to the interior of the case and facilitates cable management.

    The case is absolutely great — compact, stylish, and very well-built.
    However, keep in mind that if your GPU uses PCIe 5.0, you should manually set the PCIe slot to Gen 4 (PCIe 4.0) instead of Auto in your BIOS (usually under Advanced → PCI Subsystem Settings → PCI Express Configuration).
    Otherwise, you might experience issues with GPU detection or unstable performance.
