Lian Li introduces the A4 H2O case, which despite its compact dimensions and volume of only 11 liters will allow you to install a water cooler with a 240 mm radiator. The latter is located on top of the body. Nevertheless due to the compact dimensions of the case there are some restrictions: if the radiator thickness is 30 mm The thickness of fans should not exceed 25 mm. However, if you abandon liquid cooling , you can install conventional fans with dimensions of 120 x 120 x 25 mm.
