I have spent hours on newegg looking at different cases to give me the best cooling before building my system a few months ago. This case has some of the most monsterous airflow you can get with a PC case. All of the stock fans blow upwards of 80 cfm and there are plenty of them. 3 120mm in the front, ,a 120mm on the side, 2 120mm on the back, and a big 220mm whopper on the top to blow all that hot air out. I could not be happier with my purchase.
Now with that being said the case is $160. But you get what you pay for. Especially when it comes to airflow. I hope I helped you in some way going forward:)
