I've been thinking about trying to get some upgrades done on my computer. Highest priority is a new hard drive. I have less than 5GB left... Does anyone who has built a computer know a good 1 Terabyte on-board hard drive anywhere under the price range of $80-$100 that I can buy online? Because that's all I can find, and I want to try and keep it a little cheaper than that if I can...
