The result was the November 2001 release of the VT6010 Mini-ITX reference design, once again touted as an "Information PC", or low cost entry level x86 computing platform. In October 2001, VIA announced their decision to create a new motherboard division, to provide standardized infrastructure for lower-cost PC iterations, and focus on embedded devices. Other manufactures instead produced smaller boards based on the very similar 229×191 mm FlexATX configuration. At that point, few manufacturers took up the ITX design, but Shuttle, Jetway, etc. He later designed the Mini-ITX specification. Designed by Robert Kuo, VIA's chief R&D expert, the 215×191 mm VT6009 ITX Reference Board was demonstrated in "Information PC" and set-top box configurations. In March 2001, the chipset manufacturer VIA Technologies released a reference design for an ITX motherboard, to promote the low power C3 processor they had bought from Centaur Technology, in combination with their chipsets. Some boards based around non-x86 processors have a 3.3V PCI slot, and the Mini-ITX 2.0 (2008) boards have a PCI-Express ×16 slot these boards are not compatible with the standard PCI riser cards supplied with older ITX (Information Technology eXtended) cases. Many older case designs use riser cards and some even have two-slot riser cards, although the two-slot riser cards are not compatible with all boards. Earlier motherboards conventionally have a standard 33 MHz 5V 32-bit PCI slot. Mini-ITX boards can therefore often be used in cases designed for ATX, micro-ATX and other ATX variants if desired.
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). 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. They are commonly used in small-configured computer systems. Mini-ITX is a 170 mm × 170 mm (6.7 in × 6.7 in) motherboard form-factor, developed by VIA Technologies in 2001.
