Sheet Metal CPU Casing 3D model

A computer case, also known as a computer chassis, is the enclosure that contains most of the components of a personal computer (usually excluding the display, keyboard, and mouse). Cases are usually constructed from steel (often SECC—steel, electrogalvanized, cold-rolled, coil), aluminium and plastic. Other materials such as glass, wood, acrylic and even Lego bricks have appeared in home-built cases.
