Yes, I was going to point out Tigerdirect. I purchase parts from them almost every week. I sell computers and offer computer repair too. The only way you can save is if you buy in bulk from them. It might be a good starting point for you. Or try dell, gateway and emachines(same company) but for that you are going to need a nice chunk of Change.
Why not build your own computers and sell them as Generic? That`s what I do. I sell computers under Cyber Tech Plus Computers CTPC.. So I am working on the Emblem that I can just stick on the front of the box. Eventually I want to have my own line but that is still in development.
try Tiger Direct for now. It`s cheaper to buy a bare bones system: just add a hard drive and memory and you are up and running (get monitors too)
and CD?DVD burners. I built a computer under 500.00 bucks and resold at 1050.00 with monitor and 250GB hard drive.
