    AMD has both nowadays, unless OP's software makes use of AVX-512. Then I'd say to go with Intel.

    1. You shouldn't need one at all, unless you want to do some kind of rendering of you final simulation to present in a slide or something, then a cheap GPU should me more than enough (a 1050 or a 750, for example)
    2. A 550w should be more than enough.
    3. A big air cooler should do the trick, like the noctua nh-u14s
    4. Most issues have been sorted out already. CentOS 8 probably has everything backported into its kernel.
     
    As someone said before, you could give a look at the 3950x or even the newest threadripper lineup.
     
    More expensive and worse performance due to mitigations and older arch.
     
    Most CFD stuff can't be GPU accelerated. And, even when it's possible, it requires a double precision enabled card, which means high-end Teslas, or older Quadros/Titans. Even a K80 smashes a 2080Ti when it comes to FP64.

    No idea if what you're doing can be GPU accelerated, but if it can, you could potentially be missing out several folds of performance. No, you do not want to cheap out on PSU for something that will be running full power for extended periods of time. A properly designed airflow should be sufficient with just air coolers. Liquid cooling solutions are not economical in terms of performance per dollar. Not sure, I've heard about some issues with Ryzen and Linux.

    Is your software limited by the number of threads available?  If not, I would think that the Ryzen 9 3950X would be the best bang for buck at the moment.
