💡 How to pick a case

★★★★★Good air flow but short fan and rgb cables
Good included fans and airflow. Cables for audio, fans, and rgb are too short to stay in the cable management Chanel so thwart cable management. Getting Accessory box out is a Chinese puzzle. It’s behind the case, but instructions for opening case are in the box. And the box is crammed into disk slot so hard that I had to rip box apart to get it out. Kind of like buying a safe with the keys locked inside.

★★★★★Awesome case. Inflated price
The case is amazing. The price however, is $50 more than regular MSRP. So it’s up to you if you want to pay an extra $50 for the availability since it was sold out everywhere else when I purchased mine.
