So, I've had my PC for about a year, and its been great. But I've run out of space. I have lots of games, photos and other media and I've filled up my 1tb pretty fast. With Christmas coming up, I'll be able to get a new one. Which one should I get? At the moment I've got a seagate barracuda 3.5" SATA III ST1000DM003 1tb. But since my PC has only 3 hard drive bays, would it be better to get a 2tb one? Also, what cables do I need to install it, and where do I install it in my Aerocool Aero-800 case? Thanks.
