I'm attempting to do my first solo computer build. I was wondering whats the best place to start. This computer is gonna be multi-purpose for mostly gaming and multimedia (movies and music mostly). The guy at a local computer store said to start with a case and build around that and another guy told me to start my build around the motherboard. I have a graphics card, networking card, and two CD/DVD burner/players. I'm looking to do around 4 gigs of RAM but other than that im totally lost as to what to get from there. Im not looking for a "super computer" that will be able to put a mortgage on my house. Just a build around 800-900$. Any help would be greatly appreciated.
