Even LinusTechTips has some decent content for server hardware, though they stay fairly superficial. And the forum definitely has people who can help out: https://linustechtips.com/

And the thing is, depending on what metric you judge performance by, the enthusiast hardware may very well outperform the server hardware. For something that is sensitive to memory, e.g., you can get much faster RAM in enthusiast SKUs (https://www.crucial.com/memory/ddr4/BLM2K8G51C19U4B) than you'll find in server hardware. Similarly, the HEDT SKUs out-clock the server SKUs for both Intel and AMD.

I have a Threadripper system that outperforms most servers I work with on a daily basis, because most of my workloads, despite being multi-threaded, are sensitive to clockspeed.

Indeed, serious people now use gamer computer parts because it's just faster!

It's not "just faster".

No one's using "gamer NICs" for high speed networking. Top of the line "gaming" networking is 802.11ax or 10GbE. 2x200Gb/s NICs are available now.

Gaming parts are strictly single socket - software that can take advantage of >64 cores will need server hardware - either one of the giant Ampere ARM CPUs or a 2+ socket system.

If something must run in RAM and needs TB of RAM, well then it's not even a question of faster or slower. The capability only exists on server platforms.

Some workloads will benefit from the performance characteristics of consumer hardware.

The desktop used in TFA supports 1 TB of RAM.

Workstations and desktops are distinct market segments. The machine in the article uses a workstation platform. And the workstation processors available in that Lenovo machine clock slower than something like a 5950X mainstream processor. The RDIMMS you need to get to 1TB in the machine run much slower than the UDIMMS I linked above.
