The best way to choose a desktop computer chassis
In the process of saving a computer, the most easily overlooked part of the process may be the chassis. DIYers installing most of the CPU, graphics cards, motherboards and other major components carefully analyzed, to find out the best price-performance configuration or the most important thing for them. The most important thing is that you have to be able to get the most out of your computer. But the value of the lower content of the things do not pay attention to, that these are? I'm not sure if I've got it all. The chassis is in this forgotten corner. Forgotten corner? The chassis is one of the components in this forgotten corner. The most is to choose the chassis only pay attention to the appearance of a good look, and do not care what brand ah, model ah, not to mention the material ah, workmanship ah and so on. Therefore, we will see, in the allocation of the machine, usually after buying all the accessories, found that the money left is not much, so picked a better power supply, and the chassis will have to make do to buy a cheapest, at most, when you see the appearance of their own very like, hard heart, buy a beautiful. Anyway, we think that the chassis is just a fixed accessory device, as long as it looks OK, that what chassis can be, all kinds of brand quality difference is not big.
In fact, this is a misunderstanding, chassis as a computer accessories? The first time I've seen this, I've seen it on a computer. More should be subject to DIY attention, not only because of its quality of the relationship between the ease of disassembly of the computer, but also related to the location of the coordination between the various accessories. Here are a few examples of the mistakes we've made:
1) Thinking that the chassis is just as good as the electronics, the lighter and thinner it is, the better.
Oh, chassis this thing still belongs to?
However, the chassis is still a part of the heavy industry. The first time I've seen this, I've had a chance to see it in action. After all, the chassis is not the kind of thing that is put on a good fixed things, occasionally we still have to move a little bit, if it is a thin chassis can withstand moving? I have seen an example of this, a friend to move the computer to a place, the results of the boot when the XP in the first into the system died there, at first thought it was a software problem, the results are reinstalled, and with a floppy disk antivirus, engaged in a day of problems still exist, really can't do it, I pulled over, I live as a dead horse, the chassis is disassembled, inside the things have to dismantle the eight pieces, and then in a piece of it to be mounted! On the results of the problem to find out, we think about the problem there? Oh, a lot of people must think that the accessories problem, either this is bad, or that burned, because we all know that XP on the hardware requirements of high, we know that the performance of this bad, characteristics ah. But the problem is actually out of the case, because my friend in the purchase of computers on a random case, the results of that JS gave him a very thin computer, the results in the move, the back of the case deformation, the graphics card from the AGP slot inside the extrusion of a little bit of the result of poor contact, resulting in the inability to enter and exit the XP system. Oh, after this, my friend was careful every time he motivated the case, alas, if I had known this, why would I have done it in the first place? ^_^.
So how do you look at the frame of a chassis to see if it's good? Generally speaking, the exterior of the chassis is usually composed of a layer of steel plate more than 1 mm, the thickness of the steel plate and the material is directly related to the rigidity of the chassis as well as sound insulation and resistance to electromagnetic radiation. Regular manufacturers of chassis used steel plate thickness are not less than 1.3mm, but there are some small manufacturers use only 1mm thickness of the steel plate, we do not need that ruler to measure, as long as you run him up, the heavier the chassis in the same volume, the better, in addition, you can also use your fingers to play the shell of the chassis. If you can hear the crisp knocking sound to prove that the chassis steel plate is relatively thin and brittle, if you hear a more dull and heavy sound that the chassis selection must be good, a good steel plate is generally plated with a very thin layer of zinc (bright part), in this case, can withstand the strength of high impact resistance, hardness and elasticity. Chassis frame part of the steel used is generally a high hardness of high-quality materials folded into the shape of an angle or strip, we can remove the shell of the chassis frame vigorously with a hand shake. Good chassis should be more stable, while the poor quality chassis light is easy to shake. Selection of the time to pay attention to the chassis outer and inner bracket edge incision is smooth, a good chassis will not appear chassis burrs, sharp mouth, burrs and other phenomena. The poor quality chassis appear the above phenomenon, if the installation often appears ? Blood splattered? Generally speaking, the chassis has to go through the corresponding edge grinding treatment before leaving the factory. Some of the steel plate edge burrs are smoothed, the corners are rounded, and some corners will be folded up accordingly. When installing such a chassis, you won't have to worry about cuts, and some poorly made chassis are often easy to scratch your hand.
2) Focusing too much on appearance and ignoring heat dissipation and positioning.
This problem is often more prominent in MM. As people's tastes improve, many manufacturers have launched personalized chassis to meet the high demand for appearance of those users. Indeed, the computer is still very eye-catching at home, in addition to the role played by the role should also be a good appreciation of the product. Now the market has a lot of bright colors, novelty shapes, transparent cases and other designs to promote individuality, greatly attracted the eyes of consumers. However, often behind these shapes is the hidden danger of heat dissipation and the hidden danger of accessory positioning.
Now many manufacturers have introduced a small and exquisite chassis, and some modeled after the style of the all-in-one PC, launched a number of mini chassis, so that many of the beauty of the mm tend to, and a lot of fashionable gg also joined the ranks of the purchase. If it is the design of a famous manufacturer, many heat dissipation problems can be improved through the internal air duct design. But if it is some inferior imitation products, in the false appearance at the same time, bring more is the problem of heat dissipation and the positioning of the accessories of the problem. Reasonable chassis structure design, in consideration of the appearance of the same time, must pay attention to the chassis air duct design, that is: in the natural windless conditions, where the wind is the most appropriate, where the wind into the best effect, where the wind is the smoothest (not so much as to make the heat stagnation in the interior, can be quickly excluded from the outside of the chassis). At the same time, we must also consider the size of the wind hole and its location, in and out of the location of the fan is designed to form an effective convection and so on, these are the most basic requirements of the air duct design.
And many?
