Very interesting, but be careful about internet... It could reached easily Intel and shut down the akitio thunder2.

THank's for the thread!

Did you try BF4 for a long run? Like a multiplayer game during 1-2hours? The performances are stable?

(I assume that my 2013 late MBP retina with IRIS (non pro) must be 100% compatible?)

Yeah, thanks a lot for your tests!!!

But I arrived at the conclusion that a mini-ITX gaming system is the best solution. What's the point to have an external screen/GPU/PSU/Motherboard (close to)/housing ? At the end the only part of the laptop you'll use is the memory and the CPU.

I was interested by the challenge, but now I'm about using my MBPr (late 2013) for lightroom/web/movie/... under OSX. And a Mini-ITX for gaming under Win8.1.

A big NAS would be the only "cross hardware" between the two, for data accessibility.
