You work as an End User Support Technician and your employer is preparing to purchase new desktop machines for all employees in the office building. The CEO is cheap and wants to pack as many people into the existing office space as possible over the next year. The number one priority is avoiding the need for adding additional office space. What type of form factor would use up the lowest footprint in the office and allow the CEO to pack everybody in like sardines?
Correct Incorrect Unanswered
Answer Description
mITX or mini-ITX is the smallest form factor of the options, followed by micro-ATX and then ATX being the largest. BTX is a form factor that is not common or easy to find on the market, it was intended to replace ATX but never grew in popularity.

Mini-ITX is a 170 mm × 170 mm (6.7 in × 6.7 in) motherboard form factor developed by VIA Technologies in 2001. Mini-ITX motherboards have been traditionally used in small-configured computer systems. Originally, Mini-ITX was a niche standard designed for fanless 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.
Mini-ITX motherboards have only one expansion slot. Earlier Mini-ITX motherboards had a standard 33 MHz 5V 32-bit PCI slot, whereas newer motherboards use a PCI Express slot. 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. 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.
The HiFive Unmatched RISC-V computer uses a Mini-ITX form factor.
