💡 How to pick a case

★★★★★Modern Old School
I'm using this case for a linux server with multiple enterprise drives for network storage and container hosting. The tower looks dressed for the role compared to a mesh or glass gaming tower. It's built to reduce noise while still allowing for great airflow. Top and side panels are customizable for additional fans/airflow.

★★★★★Perfect for non rack server
Needed a case that supported several 3.5” drives but wasnt a full rack size factor. Also wanted enough space to support a CPU and GPU as well. This case does it perfectly. Able to fit air cooler and GPU and has plenty of space for all my hard drives. Would recommend

★★★★★Well Constructed and Beautiful
This is the best, quietest and most elegantly beautiful case that I've ever owned. It's inspired me to upgrade the rest of my office to match it.
