Hey tre87, thanks for the post! I'm trying to build an eGPU similar to yours. I have the same macbook (mid-2014 i7 with dGPU) and just purchased the Akitio, Evga 970, Corsair 550w, coolmaster elite, x16 riser and they should be arriving in a couple of days. I was just wondering what type of plastic board you used and what dimensions would fit into the coolmaster. Also I own a hand-drill and not an electric drill, would that be enough to drill holes into the plastic or would the platic be too thick? And did you use the thunderbolt cable included with the Akitio or would you recommend buying an apple brand one?
