So my rig is 7 years old, some parts are even older. I have a budget of $2000, prefer to be less 
I'm going to use a 1.5TB hard drive from my current build, that's why it isn't in the list.
This is what I have so far, any advice would be welcome! Also do you recommend using Newegg or Amazon? Amazon Prime seems like better shipping and the prices are identical in most cases.
