I'm going to build a new i7 computer with a i7 950, p6x58d-e mother board , antec nine hundred-two case, seasonic x650 PSU, 6 GB of corsair memory, and a GTX 580. I added some arctic silver thermal paste and windows 7. I will be reusing the hard drives from my old computer. This is my first computer build, so idk if there is anything I have overlooked that I might need to put the computer together. Help would be appreciated.
