As an alternative, I can recommend getting a used tower Mac Pro and upgrading it. There's a ton of community info [1] [2] out on CPU, GPU, and RAM upgrading, and even the oldest 2006 model, the one I have, can run El Capitan, and the 2009-2010 models can do Mojave. There are guides for every configuration you could want and RAM is super cheap (even ECC!). You get as good a case or better than if you build a standard ATX hackintosh - 4 3.5" bays + 2 optical bays you could get more drives into, and the upside-down GPU prevents sag on the PCIe connector. And you get to be "legal" within Apple's T&C, so you could use it without worries in a business/academic setting.
