A Brief Introduction of Computer Cases

A computer case is also known as a computer chassis, tower, system unit, cabinet, base unit or simply case. Sometimes, people may call it the “CPU” or “hard drive”, which is totally wrong. A computer case holds the components that make up the computer system, usually excluding the monitor, mouse and keyboard for they are separate. Generally speaking, computer cases are made from steel (often SECC — Steel, electrogalvanized, cold-rolled, coil) or aluminum. Plastic is also used by the manufacturer from time to time. On the other hand, some common material may be adopted by people when making home-built cases. For example, glass, wood and even Lego blocks may be taken use of by people. Another thing people are supposed to pay attention to is that a computer case can come in various sizes and models according to the requirements of the user and many other important factors. Therefore, people will have many choices to make in order to have a better experience in terms of computing and enjoy more convenience, which can bring them a lot of benefits.

As we all know, a computer case has a variety of sizes (known as form factors). There is no doubt that the motherboard is the largest component of the majority of computers, so the motherboard plays a vital role in the determination of the size of the computer size. As a result, the size and shape of a computer case is different from each other because the form factor of the motherboard is various from each other. In addition, the form factor of the personal computer typically specifies only the internal dimensions and layout of the case. Meanwhile, the form factor for rack-mounted and blade servers may include precise external dimensions at the same time for these kinds of cases must themselves well fit in specific enclosures.
