Then your path forward is clear: Build a Hackintosh.
You best believe that Apple watches the Hackintosh community like a hawk, and if it REALLY started to take-off, two things would immediately happen:
1. Apple would lock-down macOS solid, using some sort of Trusted Computing hardware on the mobo.
2. There would soon be a tower Mac again.
But since Apple sees that the pirating of macOS and the interest in Hackintosh forums hovers in the .5% world, as far as loss-of-sales-revenue goes, they haven't done any of the above.
So, what I am really saying is, once you get away from the internet forums, out in the REAL world, the REAL interest in a classic-tower Mac is actually pretty damned small.
Totally agreed.
Specially today, people are doing things for the web, full HD would do just fine. Youtube proved something... what matters is the script, the content, not the resolution or video quality. The best videos may be recorded with a cheap camera, no color correction and they make loads of money. While you can make videos with Red cameras in 4K an not make a dime.
So... along time ago technology satisfied the market. Unless people start to produce virtual reality from their iPhones in 8K... there is no need for more processing power for the masses. People do not need 4K at all, is over killing. We are fine with HD. Stories lines do not need filters, lens flares and stuff, they need a good script.
