this is the 200 mm fan already in the HAF 922. the HAF 922 already has great airflow. placement of the fans is more important than quality. the best thing to do would be to get another 200 mm fan (above) and put it on the side. the rest is all good, the only other place i could imagine is putting a 120 mm fan on the bottom, both the 120 and 200 mm fans being intake, while the top 200 and rear 120 mm fans being outake. and the front 200 mm being intake.
