"that thread by BassThumper had us working overtime" LOL

LuciusThorne,
Given:
"Price is not a significant concern for me."
"I don't necessarily need high-end graphics."

In my opinion, a good choice would be Intel Core i9 minimum "10900k" processor system. Preferably, it should have at least two USB-C 3.2 ports - they are fast and also allow for Video out, similar to hdmi. And a fast SSD / nvme drive., Samsung 980 pro or similar.

If you have or planning to get Audiophile version of BIAB, that you want to run from internal drive, you might want to consider a separate 4tb SSD.
