This is my attempt to create my own case. The main goal is good cooling capacity and good airflow. Also symmetrical design, it can be used on both left and right sides. I wanted to have minimal dimensions of the case itself. So I used 2*280mm radiators, a mini-ITX motherboard and a SFX PSU. The GPU can be almost any length up to 285mm. The reservoir is standard 50mm diameter. No custom parts, everything is stock. Overall dimension 319x155x396mm.
