I have a nice rig with i7-4790K (water cooled by AIO), Asus Z87-WS, EVGA 1300W Gold PSU and 4 GTX 1070s. I would like to water cool all of the GTX 1070s but, they are all different. I found an adequate AIO for GPUs which is ID-Cooling Frostflow 120VGA but, I have no idea about what case would accommodate the 5 radiators. Do you have any idea about an adequate PC case? Thanks in advance for any help.
