Hello i've been reading for the past few days but I am so lost i've had to make an account. I have a mid 2014 top end rMBP with the 750m, but i've just ordered a late 2012 mac mini (wanted the quad and upgradeabillity). Im looking into the eGPU for the mac mini, I understand that my mini has thunderbolt 1 where as my macbook is thunderbolt 2. So far from what I've managed to understand is that I would need to buy the Akitio case but from what i've read above, would i not need to mess around soldering anything? I was looking at this GPU Asus GTX 970 mini.. although i'll probably end up going for a cheaper one. Because thats smaller I wouldn't need the powered riser? Or is the revelation above that you don't need a powered riser at all? Also how do you get power to the graphics card? Basically I just need a step by step dummies edition of the whole process. Im not afraid to get my hands dirty and learn some new skills, but the only thing that is putting me off is doing it wrong and blowing an expensive graphics card...
