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.

11-Liter Form Factor

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.
