Had fun building in it. Squeezed in an 7900xt GPU without a problem. Great airflow and access. Highly recommend if you are looking for a case that a different form factor.

I love thermal take cases. I had my last one for 10 years and it survived 3 moves. But this case just looks great and has great airflow. It was very easy to figure out and hides all the cables great. I didn’t even build a new pc I just moved every thing into this case and it feels like a brand new pc. 10 out of 10 would recommend.

This is for my husbands gaming setup. It fits on a IKEA square shelf on the top, it’s too small to fit inside but it looks great on display sitting on the top. Our old ones were also on the top but they hung over and didn’t look as aesthetically pleasing!
