Small Form Factor

Small Form Factor (SFF) is an umbrella term for computers and hardware components designed to be significantly smaller than standard sizes. In the desktop PC world, a system is generally considered SFF if its case volume is under 20 liters, compared to traditional mid-towers which often exceed 40 liters. Key Components of an SFF PC

To build or buy an SFF PC, standard hardware must be swapped for specialized, compact alternatives:

Motherboards: SFF computers primarily use Mini-ITX motherboards, which measure just 6.7 x 6.7 inches, rather than standard ATX boards.

Power Supplies (PSUs): Instead of bulky ATX power supplies, SFF builds use compact SFX or SFX-L power supplies.

Graphics Cards (GPUs): Builders must carefully track the length, width, and thickness of GPUs to ensure they physically fit inside the smaller chassis. Pros and Cons of Small Form Factor
