My new case wont be here til Monday:,( I wondered if I can get a jump start on anything. I have every part except the case and coolmaster cpu fan. I really don't want to break out the mobo, cpu until the case gets here. Have a 3yo and a cat. Can I hook my 1bt Seagate hdd and crucial 256 ssd and start adding my games and other must have files before hand? I have a corsair 430w psu in my current pc and I have a stock hp w 750ti gpu. So Im unsure if I have an extra cable to hook up and additional hdd. Has anyone done this sort of thing before?
