Is your computer’s case or casing of any importance to you? You may be asking yourself the question: why should it be? The fact is that the computer case is important to the computer itself and also to some people.

Let’s begin from the computer’s point of view. One, if not the main causes of computer malfunction is too much heat. Which is why, when computers were first used in factories and large offices, the specialized computer room was isolated from dust and was air conditioned, if not cooled specially. In those days, thirty-forty years ago, computer components were very fragile and extremely costly.

Nowadays, they are very, very much less expensive but they are still subject to bother from heat. Extreme heat will twist the boards, especially the motherboard because it is large, inside the computer case. They are not made for these gymnastics and sooner or later the very fine connections soldered onto the surface of the board will crack and prevent the flow of electricity. It will die.

In order to inhibit this happening, manufacturers put fans inside the computer so as to increase the flow of air. There are normally at least two in a desktop computer case, one fitted in to the external casing and one directly on the CPU (the chip), which is often the hottest and most expensive single component. In laptops, where air circulation is even more limited, there may be three or four fans.

So, these fans increase the circulation of air within the case in an attempt to cool the chip’s surroundings down. Therefore, it also stands to reason that there must be sufficient space for that air to flow. If it was left up to the computer to design itself, computer cases would be larger and with more fans. A little like you might like to live in a larger house with air conditioning, if money was no object.

Now from the human’s point of view. People agonize more about looks and fashion and about how much space the computer is taking up. Producers have to pay attention to what people would like if they want to sell their computers. People wanted less obtrusive computer cases, so manufacturers made half-size cases; people wanted less noisy computers, so manufacturers put fewer fans in the cases. And the result was unsurprising: computers housed in cases like these broke down more often and the only person who was happy about that was the producer.

There is also a trend towards beauty in computer cases. Acrylic, see-through cases are very trendy with gamers. Now games machines are some of the most powerful home computers on the market, because of the power needed to run the graphics at a life-like speed.

See-through cases encourage the use of size and fans, because they are often themed, which means that the interior may have green, blue, yellow or red LED’s to light it up. So, for instance, when the DVD player kicks in a red LED comes on inside the case. Similarly with fans, which may also be painted. Some of these themed computer cases are ideal for the chips that reside in them and the individuals that own them

Shoppers in this new millennium are much more knowledgeable about electronic goods than people were at any time before. The older generation of today grew up in the 1960′s and 1970′s when everyone in the West had a television set and a stereo. Previous generations were not so lucky for financial and technological reasons. Therefore, most shoppers nowadays have no compunctions about going shopping for complicated electronic equipment like a home theater.

It is in the shoppers’ best interest to research and understand about the components that go into making up a good home theater. It is not particularly exacting and many if not all of the elements involved have been around for at least a few years now. Consider what goes into a home theater:

a screen – can be a television screen, a canvas screen for a projector or a modern plasma or LCD screen. Forget about the modern varieties of screen, they are still fundamentally TV screens and they have been around for 80 years or so. Same with a projector.

a player – a DVD player is just an improved CD player and they have been out for 20-30 years. You have probably had one for most of that time. (You can add another dimension to your home theater here by swapping an Xbox for the DVD player, but games machines are not new).

speakers – they are nothing new either. Speakers have been about as long as the television set.

So you see, there is nothing in that kit which you should feel awkward about buying. Fair enough, you will be buying state of the art examples of what I listed above, but they are fundamentally the same. You connect them all together with their special plugs and wires and then plug them into the mains. Switch on and it will work.

So the next issue is: do you buy a package or do you buy the elements and build your own home theater? The answer to that question really depends on your level of competency. A package is easy and may work out less expensive too, but will it have the flexibility that you want? If you have a standard sized and standard shaped room, then I am convinced that you will be able to buy a package that will suit you. If you think that the speakers are sub-requirement, you could always sell them on and upgrade after a while.

if you want to be sure of getting exactly what you want, I think that most people will have to buy the elements separately: that is screen, player and speakers.

The size of the screen depends on the size of the room and how close you are sitting to it: a distance of between three times and five times the diagonal of the screen is approximately right. However, some people like to be dominated by the screen and others do not want to wear their glasses, so it is up to individual choice.

The DVD player is a matter of personal preference too. They are all much of a muchness, but some people prefer Sanyo while others prefer Philips. If you want gaming functionality too, use an Xbox instead of an regular DVD player.

Most rooms will require at least a 5.1 surround sound speaker set. These should be acquired as one package to make certain that they are all compatible. That is five normal speakers and a sub-woofer.
