Being that I'm a novice at building a Computer , Is their any chance i could build a good gaming/ work computer myself for under $!000?
Yes, you certainly can. In fact look at the toms system builder marathons on the front page and look at their builds in that price range. That will guide you to a selection of parts.
As for the actual construction, search the net and you will find articles on how to do the assembly.
If you elect to do this, you know that you can come to the forums on this site with any problems that you have.
