The airflow was very good and I liked the large size and it was easy to build inside of and I really loved it the build experience and it looks great with my monitor and keyboard.

If you're looking for a case with plenty of space and air flow, this is it. Having the option to install fans on the bottom is a great addition to create more air flow to keep all your parts cool and running efficiently. Has plenty of space to add any GPU you would want to install. Also, being a dual chamber case helps keep all your parts installation a breeze. And cable management is super easy with this case. I would definitely give this case an A+ since it exceeded all my expectations.
