I am still learning about the whole overclocking deal. It is something I would like to pursue, just not sure how to go about it yet. After reading several reviews I will go with the tuniq tower. I am still debating Hard drives- I am not learning towards anyone in particular right now, i'm still reading reviews and comparing them. I have heard good things about the 1TB drives from Seagate and Hitachi. Is there any downside / benefit to having a single 1TB HD as opposed to say a 1 x 120 GB HD and a 1 x 750GB HD?
