PC tower cases are often misinterpreted as CPU. CPU is actually the components housed within the case. The tower case is the enclosure that contains most of the components of the computer which doesn’t include the display, keyboard and mouse. It can also know as a computer chassis, cabinet, box, tower, enclosure or simply the case.
Such of the chassis are usually constructed of steel, aluminum or wood. Sometimes they are also made up of plastic and can also be found to have been home-built out of Lego blocks. Along with the materials used to build up a case, there are also different sizes and shapes available. The size is usually determined by the form or the size of the motherboard, since it is the largest component of most computers. Thus, the size of the chassis is actually the result of the internal and sometimes the external dimensions of the case.
Yet, when it comes to grouping the cases on the basis of the sizes, the tower can be grouped into big-tower, mid-tower and mini-tower sizes. The big-tower cases are generally 22 inches or more in height and are designed to stand on the floor. They have six to ten external drive bays. The mid-tower cases are smaller in comparison to the big-tower cases. They are about 18 inches high with two to four external drive bays. Similarly, the mini-tower case is 14 to 16 inches tall and has only one to two external drive bays.
Most of these enclosures have a specific design with various facilities. These usually have power supply unit, drive bays, peripheral connectors and expansion slots. Most also have a power button, a reset button and LEDs. Some also include a built-in I/O ports; such as USB and headphone ports on the front of the case. The appearance has also differed from the early days of the introduction of PCs. Although most of the PC cases are designed in a simple rectangular shape, there are a few, unique and creative shapes available too. They are usually found painted in the colour beige or white.
There have been some unique styles that the cases are found in. some have clear side panels or acrylic windows so that the users can look inside while it is operating. Such cases are termed as Case mudding. These may also include lightning, custom paint or liquid cooling systems. The recent of the cases also include the “screwless”. These don’t require screws to hold components and panels in place like the traditional cases did. In the latest the components are held together with snap-in plastic rails, thumbscrews and other methods. These of the new techniques facilitate quick assembly and modification of computer hardware.
In conclusion, there is a whole new world to the meaning of tower cases. It no longer has to be dull but can be as unique and stylish as you wish. Some hobbyist also design and custom make the cases out of many raw materials, leading it to become cool and chic.
