Hi Mike,
thank you for the answer I will try to contact EK.
Well, the problem (it might not even be a problem :) ) is that this GPU has its own water cooling loop. And I am not really sure if this chassis is prepaired for this option. I cant change the water loop in here and the water pipes on this GPU are just 20cm long, so I dont know if it will be enough to reach the fan mount spot to be able to mount the radiator in there. I hope you can understand how I mean this, I know my English is far from perfect, I am sorry for that :-) If not, I will try to paint it for you! :D
