Hi. I have been planning to buy a used oem pc from ebat with a sandy bridge processor to be a budget system like I have seen many others do. My question is how much should I pay for one? The one I am looking at is a optiplex 790 with an i7 2600,8gb ram, and a 500gb hd. The price is asking for $170 while I have seen others get one for way less. So I was wondering how much you would pay for. Thanks!
