ok, i'm pretty much a complete nooby when it comes to building a computer. i'm just wanting to be able to surf the web, play some halo 1/older games, and not have my computer catch on fire and crash. right now i've got a few year old basic compaq...any suggestions on how to build a decent computer from the ground up? i talked to some people at micro center and they told me it'd cost about 600-700 dollars to achieve that...sounds a lil steep for surfin web and halo 1, but i've been wrong before...well, lay it on me, and i'm here to learn, so tell me the differences between various products, never hurts to actually know what to get AND why to get it, much appreciated
