It's better to go to your local electronic store and let them design your PC. It's way cheaper and if you let them assemble it, you'll probably get a warranty for 2-3 years. I think not positive about that. But just tell them your wishes, like what you are going to use it for, what you want to pay for it and some of the parts you really want. E.G. intel core or hard drive. I've done this myself and I've got a pretty goddamn awesome PC for under €1000. I don't know if you want to spend that much, but just think what you're really going to need.
