I am going to watercool a Define R3 and i am wondering if it's smartest to have a 240mm or a 280mm rad in the front. i am debating this since the space between the fans makes a 280mm fit but at the same time its to wide since the fan mounts are for 120mm fans and then i am going to have to make new holes for the rad mounting. then again a 240mm would be to short to get maximum out of the airflow. what do you think?
