The form factor of a motherboard determines its physical size, layout, and compatibility with PC cases, power supplies, and expansion options. Popular form factors include ATX, Micro-ATX, Mini-ITX, and SFF (Small Form Factor), each offering different balances between expansion capability and compactness. Larger form factors like ATX provide more expansion slots and ports, while smaller ones like SFF are great for space-saving builds. For example, the Gigabyte Z390 is ATX, offering expandability, whereas the Dell OptiPlex 3020 is SFF, ideal for compact desktops. The Lenovo 14e Gen 2 Chromebook uses an ATX form factor as well. With these options, you can select the perfect laptop motherboard form factor to fit your space and performance needs.
