Those who have professional knowledge of computers will look will be more interested in finding out what its expansion capabilities are, its noise level, convenience, protection provided and very specially about cooling because a computer that generates lots of heat in view of the highly demanding tasks expected of it will definitely need more cooling fans to keep the machine from becoming overheated and damaged.
Standard computer cases usually have one or two fans that are more than sufficient to cater to the needs of the average user who will most probably use his computer for basic work in the home and office. Anything more demanding will require additional cooling features such as strategically placed openings in computer cases and the best place to keep the airflow paths free from blockages.
All computer cases typically have a power button with LED lights to display the status of power and are directly connected to the computer motherboard which is inside the case. The rear of computer cases consist of various slots including that for the power cord, mouse, keyboard, for the DVD drive and ports for extra features all of which are mounted on the motherboard and connected to externally. Gaming cases however have to be specially selected because they require extra cooling and therefore needs better air flow and additional bays for internal and external components.
Although the appearance of gaming cases have no impact on the performance of the system, most gamers prefer to have good looking gaming cases with the most popular being those that have transparent look through side panels through which you can look inside. Gaming cases are made out of different material such as aluminum, steel, fiber glass and even plastic; but steel cases are the most expensive because they are acoustically quieter than others.
The above mentioned motherboard is one of the most complex features of the computer and is fitted with hundreds of components that no layman can easily identify. Considered the heart and soul of the computer, the motherboard is the central exchange to which all the other components are connected to as explained earlier. Although they come in various sizes and shapes most motherboards are compatible with standard computer cases and pose no problem when you buy the complete unit. Its only when you try to input a new motherboard in to an old case that the process becomes tricky.
RAM is a sort of temporary working area inside the computer and does not store anything. The moment you turn off your computer whatever you have been working on vanishes. Fair enough don't you think because RAM stands for Random Access Memory. But the problem is, if your computer doesn't have enough RAM there's no space to carry out the work and it slows you down and that's why you require sufficient RAM to get on with your work uninterrupted.
