23-ComptIA A+ 220-901 (Mini-ATX ) by IT Training and Tutorials | English

Mini-ITX is a 17 × 17 cm (6.7 × 6.7 in) motherboard, developed by VIA Technologies in 2001.They are commonly used in small-configured computer systems. Originally, they were a niche product, designed for fan-less cooling with a low power consumption architecture, which made them useful for home theater PC systems, where fan noise can detract from the cinema experience. The four mounting holes in a Mini-ITX board line up with four of the holes in ATX-specification motherboards, and the locations of the backplate and expansion slot are the same (though one of the holes used was optional in earlier versions of the ATX spec). Mini-ITX boards can therefore often be used in cases designed for ATX, micro-ATX and other ATX variants if desired.
