No. Don't do it. Buy it store bought already built. What you are saying makes no sense because you are saying that you get some parts for half price, but then you will have to spend money to have somebody put it together for you. So it will cost you more money in the long run. Don't build your own. You will run into problems. Processors and mothersboards are outdated almost as fast as they are put on the shelves. The newest processor is a quad processor. It took the place of the dual. So if you are getting a good deal on a dual, then it really isn't a good deal at all, but old stock that they are trying to get rid of.
