Very interesting in using the old cheesegrater towers. I too followed that path, first 2 SSDs on a PCI card as an array, then a GTX 980 in a 2010 5,1 native machine. Only thing I am very unhappy about is the bit about 10.13, APFS and running from a boot SSD array. They SAID I can do it, but lied and have NOT addressed the issue at all. I continue to run Sierra.
One thing caught my eye, regarding running win10 on such a machine. The article said something about installing it "so it doesn't appear to be a "boot camp version" so he can update the GPU drivers." Is this specific to the AMD GPUs and the fact the fruit builds said drivers into the underlying OS? I DID play around with a win10 Bootcamp thing, and while it was working fine, I was able to install whatever the latest nVidia drivers were for my GTX 980. Did run some kinda game focused graphics benchmarks, it seemed that setup ran faster than the Mac side for one game (WoW) and very competitively for win boxes with roughly equivalent CPU/GPU combos. Unfortunately, I tried to install some LogiTech mouse drivers and somehow that whole system got borked to the point where I could kinda boot it, but none of the diagnostic or repair utilities it would run got it to fully boot. BUT am curious about the "installing win10 without it thinking it's a Bootcamp version." Anyone got a link to where I can find how to go about that?
