The computer case. Features

Everyone who has had to independently assemble a personal computer from individual components knows very well how important a good case is. It only seems that this detail is very insignificant and is only needed to hold all the details. In fact, the computer case performs one of the key functions - it allows to organize the correct circulation of air streams that divert excess heat. Note that it is not necessary to build the system unit - a neat person to perform cleaning and maintenance, the computer case has to be opened several times a year. At least, such a periodicity is recommended. A product of poor quality often leads to the idea that it would be worth not to buy, but to make a case for a computer with your own hands.

Now most of the buildings sold are manufactured in China, and the one that is neglected by "Chinese consumer goods". We have already pointed out that beginners often do not understand the importance of this element of the system unit, so when you buy, they stop their choice on budget models. Not surprisingly, such products fully meet expectations, being just a holding frame. Let's briefly go through the peculiarities of state employees.

The computer case can be made of processed aluminum or steel. Inexpensive models are made of cheaper metal, and, as a rule, insufficient thickness. Because of this, even a small effort is enough to leave a small but noticeable dent after pressing the finger. Although this does not affect the functioning of the computer, it's a little unpleasant.

The next feature, which, fortunately, is encountered less and less (it is quite possible that they simply stopped buying) - these are not enough blown edges. It is obvious that metal sheets should be bent from all edges, preventing accidental cuts. Unfortunately, Chinese manufacturers do not think so. The result is cut hands with sharp edges.

The computer case is often assembled from blanks using aluminum rivets. In budget models, sometimes the size of the rivet's body is chosen incorrectly, because of which there is too much protruding aluminum, which creates the impression of an inaccurately assembled product.

Given the trend of reducing the manufacturing process of transistors in microcircuits, the problem of heat generation of components is no longer so acute as a couple of decades ago, when enthusiasts managed to cook scrambled eggs using the heat of the central processor. Nevertheless, a good body can always "boast" a well-thought-out arrangement of ventilation holes and fixtures for installing fans. The web can easily find a recommendation on the optimal organization of air flows inside the hull.

The way to fix expansion cards is a special issue. It would seem - there is a time-proven solution when fastening is done with conventional screws. However, there are several more options for solving this simple problem. For example, access to screws can be blocked by a decorative metal box, which only complicates the disassembly. Also there are several models of plastic clips. Although they allow you to fasten cards without a screwdriver, in some cases you can use them, nevertheless, it is inconvenient.

Given these features, you can choose the optimal solution. The main thing is attentiveness when choosing.

The cardinal option is to assemble the computer case with your own hands. On the forums there are many models: from simple, accessible to everyone, to the refined, requiring for the assembly of a certain experience. Used mounting foam, polystyrene, plastic and even paper.
