I can help you build / improve your own desktop. All i would need to know from you is your budget and what sort of desktop you want, e.g What you want to use it for?. I will find out what you need and provide you with the information you need to buy the parts. I can also help / guide you to set it up. This is a very cheap way to get / upgrade your computer as most businesses charge for time, labour, service and other things. This way you buy the parts and fit them yourself. Saving you some money.
