This is a first time build. It is scary but I am convinced I will get more bang for my buck and end up with a machine that does not have all the added jet when buying from a store. I mostly want to make DVD's from edited camcorder and camera data, and add my own music to the production. I also do a little bit of gaming. Will these parts provide a nice system that I can use for 5-7 years? Thanks in advance for any advice or comments you give!
