Sorry I can't help too much with suggestions, but I don't think buying used is a good idea. Buying new you get full warranty and help. Building your own you need to followup individually and send in any bad part, it is a real pain. I don't think you save much money building your own computer anymore, vs. buying a great computer with a crappy video card and just throwing in a sick one or something.
