Nano-ITX is a computer motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005. Nano-ITX boards measure 120 × 120 mm (4.7 × 4.7 in), and are fully integrated, very low power consumption motherboards with many uses, but targeted at smart digital entertainment devices such as PVRs, set-top boxes, media centers, car PCs, and thin devices.
