I have been for a couple of years. Mine is an DIY version with a PC power supply. I made it about 3.5 years ago. Last time I checked, I couldn’t use my particular setup for accelerated graphics in MacOS (I could in bootcamped Windows) but I think that works now. I just haven’t done it. I use it mostly for 3D rendering. It’s an Akitio enclosure, which was the first popular one. I use it with a GTX 980Ti with a little 400 watt power supply on a late 2012 MacBook Pro and it works great. I travel with it and everything. The performance hit is a lot less than people make it out to be. Mine runs on TB2 and I don’t remember numbers but I have done graphics benchmarks using it in boot camp Windows against the same card in my PC. It was a few FPS different on most tests. I don’t remember exact numbers. For 3D rendering/data processing, there is no performance hit.
