About this product

The A4-H2O PCIe 5.0 is an 11-liter small-form-factor case, and a collaboration project with DAN Cases. Based on the original DAN A4-SFX case sandwich layout concept, the A4-H2O continues the minimalist, compact form factor, with improved hardware compatibility (including AIO water cooling) and simplified installation. The 11-liter compact case supports a 240 AIO and a triple-slot GPU up to 322mm long. With a minimalist design featuring anodized and sandblasted aluminum panels. Previously only available with PCIe 3.0 or 4.0 riser cables, the A4-H20 is now updated with a PCIe 5.0 riser cable.

Features
  • Compact 11-Liter Design

    The A4-H2O is one of the smallest cases on the market at just 11 liters, yet it supports a triple-slot GPU and accommodates 240mm AIO water cooling, striking the perfect balance between size and performance.

  • Elegant Minimalist Aesthetic

    Featuring a premium aluminum exterior available in black or silver, the A4-H2O showcases a minimalist design with extensive ventilation, making it a stylish addition to any living or entertainment space.

  • Innovative Sandwich Layout Design

    This unique sandwich layout accommodates a triple-slot GPU, mounted behind the motherboard using a PCIe Gen. 5 riser cable. Mesh panels on the bottom, sides, and top ensure optimal airflow for direct cooling. Removable bracket supports SFX and SFX-L power supplies, with a pre-routed power cord extension to minimize hardware interference.

  • Updated PCIe 5.0 Riser Cable

    The A4-H2O now includes a 240mm long PCIe Gen.5 riser cable, to vertically mount modern GPUs behind the motherboard. The PCIe 5.0 riser cable delivers up to 32Gb/s bandwidth, which is twice the speed of PCIe 4.0. It supports PCIe 2.0 to 4.0 devices and ensures stable signal transmission with consistently high performance across wide range of GPUs.
