The microATX is a standard for motherboards and it was introduced by Intel in December 1997. It is the smaller motherboard which can be used in either smaller computer case or an ATX. The maximum size of a microATX motherboard is 9.6 × 9.6 in (244 × 244 mm). The standard size of ATX is 25% longer and the currently available microATX motherboards support CPUs from VIA, Intel or AMD.
