Small Form Factor (SFF) computers are compact, powerful PCs designed for small spaces. These mini towers fit top specs into a condensed footprint under 15 inches. Despite their petite size, SFFs perform just like larger machines. Their space-saving design makes SFFs ideal for cramped home offices, bedrooms, and flats where you want a full desktop PC without dominating your limited area. SFFs easily handle everyday tasks like web browsing, work, media, and casual gaming.
