If you've heard of Psystar, chances are you know the risks involved with buying its systems. You might also have guessed, correctly, that in this OS X Snow Leopard-based Open(Q) system, Psystar once again shows up Apple in the price-performance department. There's little else to recommend this spare system, but if fast and cheap OS X is what you need, Psystar has you covered, at least for as long as it's still around.
Specs: Intel Core 2 Quad Q8200 / 2.33 GHz, 4 GB / 8 GB (max), Apple MacOS X 10.6, nVidia GeForce 9 series
