Review: Best for compact purposes. will fit big luggage for check-in. - While nothing is really perfect, this modular case lets you style give you a lot of options for your PC. Small form factor case for your mATX (perfect fit) and ATX (pushing it a bit but still okay). Can accommodate long GPUs. You have the liberty to fix CPU components (PSU, Fans, I/O Panel) as you like. Cooling is a bit tricky but should be fine after a few arranging of parts which i totally love about it. I enjoyed arranging components to get where i wanted. Plenty of wire routing options which are stealthy for a cleaner install. While cooling takes a bit effort compared to mid-tower/full towers, Im sure this will accommodate more cooling parts and be way cooler than your regular small form factor ITX cases. will buy another one for a future project if needed.
Review: Compact - Smallest case I could find that fits a full ATX motherboard. Had to add fans to get proper airflow. Otherwise perfect for such a small case.
