The Corsair 400r is an amazing and very roomy case which means excellent cable management and excellent airflow. Tool-less drive bays and hdd bays are brilliant I must say took about 1 minute in total to get the HDD and drive in. Also brilliant airflow as you can fit up to 10 case fans, I think up to 6- 140mm fans and 4- 120mm fans. Although I only got the case today I installed the PSU (Power Supply Unit), one HDD, one SSD and an optical drive so far so good, still waiting for a few components. I have also been hearing that the fans supplied with case are extremely quiet even at full load. Note there are 2 WHITE LED fans at the front which have the option of being turned on/off with the front panel switch/button. I only encountered one problem, the delivery took a while, other than that I'm very happy with the case. Recommended to anyone or even any gamer :D
