A small form factor (SFF) case is a computer case that is designed to be smaller than a standard ATX case. SFF cases are often used for building small, compact computers that are easy to transport and store. The best SFF cases are able to accommodate all of the necessary components of a modern computer, including a motherboard, CPU, GPU, RAM, and storage drives, while still maintaining a small footprint.
There are many benefits to using an SFF case. SFF cases are more portable than larger cases, making them ideal for users who need to take their computers with them on the go. SFF cases are also more efficient with space, making them a good choice for users who have limited desk space. Additionally, SFF cases can be more affordable than larger cases, making them a good option for budget-minded users.
