MBFOs

MBFOs, or Motherboard Form Factors, are standardized dimensions and layouts for printed circuit boards that form the basis of a computer system. These standards dictate the physical size, mounting hole locations, and connector arrangements, ensuring compatibility between different components, most notably the computer case and the power supply.

The most common motherboard form factors in desktop computers are ATX, Micro-ATX (often abbreviated as mATX), and Mini-ITX. ATX is a larger form factor offering more expansion slots and features, typically found in full-size desktop towers. Micro-ATX is a smaller, more compact version of ATX, which can fit in smaller cases while still providing a good balance of expansion and functionality. Mini-ITX is the smallest of the common desktop form factors, designed for highly compact or specialized systems like home theater PCs or small form factor gaming rigs, and usually has fewer expansion slots.

Beyond these, there are other less common or specialized form factors. EATX (Extended ATX) is larger than standard ATX and is often used in high-end workstations or servers requiring extensive connectivity and component support. Smaller form factors like Nano-ITX and Pico-ITX exist for embedded systems and ultra-compact devices. The adoption of these standardized form factors simplifies the design and assembly process for computer manufacturers and allows consumers to easily select compatible components for building or upgrading their systems.
