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.
