Hi, i'm looking to build a budget pc for gaming and i'm a noob. I have no idea what motherboard to get or case and prefer something where I can upgrade parts a little down the road. The parts above are just what i've picked out with my very basic understanding and please if anyone can tell me if they know of a better value for anything let me know. Oh yeah I already have a monitor/mouse/keyboard, I also have 4 gigs of ram from my old laptop that I want to add in. I also need to know if I need to buy any wires or screws separately. Thanks Alot
Also I don't know what other parts I need, like a cooling system or heat-sink or something. Also I can go a little over $600 if need be

Also you think you can recommend me a good 1Tb hard drive that doesn't cost that much more? Sorry if i'm being a burden.
