Not just a raw board, Quadra is a complete modern Linux computer that can be used as a server or light-use desktop and includes the case, heatsink, power adapter and HDMI cable. Just plug into a TV or monitor and a keyboard/mouse. No SD card needed as the OS (Debian Bullseye) is pre-flashed in internal memory. A great option instead of Raspberry PI when you don't need the 40-pin I/O header or want something more affordable that doesn't require assembly.
