In this day and age, it is a lot cheaper to build a computer than it is to buy one. All you have to do is find a system builder and make sure you have all the right components for them to build the machine that you want.
If you decide to have your own computer built, then you might be tempted to get everything state of the art, but this would be a mistake, and you might end up wasting a lot of money.
What do you need it for?
The trick is to think about what you actually need the machine for. If you are going to playing games or editing movies, then you will need a machine with a lot of RAM and plenty of hard drive space.
If you are only using it for basic things like word processing or surfing the Internet, then you can save money on the RAM and hard drive and buy something else that you will need, like a bigger monitor, or an ergonomic keyboard.
In this case, buying high levels of RAM will be a waste of money because you will never actually use the RAM. It will just be sitting there gathering dust whilst you only perform menial tasks with the machine.
The aim of this article is to let you know which components you should buy when you are only building a computer for low-level tasks. So, read ahead for more information about building computers.
First of all, whether you are building a state of the art system, or a simple machine, you will need to have some sort of cooling system in place. Therefore, you will need to buy a small 12mm fan system. The fan will cool the system down and make sure that the motherboard does not over heat, but it will also help to remove dust from the machine. Dust can damage the motherboard, so you need a system in place to remove it, and then the computer will last a long time.
Graphics Card - All computers need graphics cards so that they can play different forms of multimedia. If you are building a high-end gaming machine, then you will need a high-end graphics card. In all honesty, you might even need two cards. However, if you are only going to use the machine for minimal tasks, then you can just buy a low-end card that does not cost as much money. A low-end card will enable you watch DVDs on the computer.
Hard Drive - With hard drives, bigger is always better because you will always have information that you need to store. Over the years, hard-drive sizes have grown from mega-bytes to giga-bytes and now they are being made with terra-bytes of space. For gaming, go for the biggest size you can get, so you might opt for a 3TB hard drive. For anything else, you can go lower, but with all forms of multi-media being digital, it is not recommended that you buy a drive smaller than 1TB.
RAM - You have probably already worked out that again, the more RAM you have, the better the machine is going to perform. You should aim for Dual RAM, rather than single slots, so if you want 1GB of RAM overall, it is better if you buy 2 x 500gb RAM. You could save money and buy less RAM if you are using the computer for less intensive
