$1000 USD is plenty to make a Dolphin PC. If I were you, I would use Zooke's build and add an internal 1TB HDD and HID as needed. His build can run modern games too, like AC4 (which I just started playing and have fallen in love) and most every game coming out in the next decade (maybe) at high settings.
