Hello, i search for a new home of my hardware and found the Level 20 HT. I use an costum watercooling with 2 360mm radiators (3x120mm fans). The thickness is 60 and 45 mm. Now my question: I plan to install the bottom radiator vertical. Which possibilitys i have in this case: Can i install the radiator outside (behind the backplate) and only the fans inside? What is the maximal thickness of the radiator? When i use the vertical installation, is the installation of fans in the bottom area possible? And what is the maximal thickness of the side radiator. Thank you for your help Guenniko
