Build a Desktop Computer

Edited by Clifford, Anonymous, Eng

There are available branded computers such as Dell, Samsung, HP, Acer and many more that you could buy pre-assembled and all you have to do is plug in the power and you are ready to use it. However nothing beats building your own computer as you can choose what parts and specs your actual computer will be. This is a much rewarding task specially the moment you finished and plug in the power as you can see the fruits of your hard work.
