I'm wondering about the theoretical possibility of Apple adding a discrete graphics chip to the Mac Mini. Is there anything stopping them, apart from obvious space-issue and power-issue? Seems to me they could just either get an external power adapter and solve both the space-issue and the power-issue with that.. or just make the Mac Mini slightly larger to make room for the chip as well as a larger power adapter? If they can fit a GTX 680MX in the iMac, I don't think it would be too hard to fit it into a Mac Mini as well. A Mac Mini with a real graphics chip would be a massive power horse for a variety of different people. Not to mention it'd be a small and very powerful Mac.
