This is a transformable mini-ITX computer case design that is trying to balance the thermal performance and noise control. The main feature of the PC case is the transformable side panels. When the computer is in high loads, such as playing games and rendering images, the side panels can open to provide much more space for cooling. When people are doing light works with the computer, like typing and watching videos, the side panels will close to achieve better noise control, providing a quiet working environment.
