A
small form factor (SFF) is a
computer form factor designed to minimize the
volume of a
desktop computer. For comparison purposes, the size of an SFF case is usually measured in
litres. SFFs are available in a variety of sizes and shapes, including shoeboxes, cubes, and book-sized PCs. Their smaller and often lighter construction has made them popular as
home theater PCs and as
gaming computers for attending
LAN parties. Manufacturers also emphasize the
aesthetic and
ergonomic design of SFFs since users are more likely to place them on top of a desk or carry them around.
