...so we can infer he used a fork, at least!

(In at least thirty-six different ways to dispatch an enemy!

)
I am entirely aware that I can clumsily put a rig together with components I can shop and buy myself, and save a lot of money, while giving myself a piercing headache over a protracted period of time. I decline to do so from decades of experience -- no one on the planet should
ever use a computer built by me, including me!

Other people can
skillfully do that themselves, and have
fun doing it, and save themselves a lot of money: definitely the proper choice, for them! I've never said any different, so there has never been any argument from me about that.
If I'm going to spend my own money hiring someone to build my computer during any particular decade, I'm going to take minimal risks for the best results over the longest period of time that I can save up money to afford. That is a logical purchasing strategy under my circumstances, and has saved me a lot of headaches over 20 years. For other people, a different strategy would be much better.
Ysk: "Also, the story about how they are able to configure and match the hardware like nobody else can is crap, you know that right?
They don’t manufacture their hardware, they are assemblers of off the shelf stuff, just like any of us building our own rig."
Also Ysk, literally five seconds later: "That said, it does illustrate that building a rig is not that simple as many sites make it out to believe. You do need to have knowledge or are willing to dive into the deeper dark arts of hardware configuration."
For which you gave a small but important and subtle practical example of this a few posts later; which I technically understand but which many people would not and which I have less than no desire to try to do myself.
FNW spends research time running their own experiments on how to configure and match the hardware they offer (including the hardware's software settings, and the bios settings, and ideal wiring and circuit paths etc.) -- they dearly enjoy doing that, they take great pride in being the best in the world at it, and their skill has repeatedly been shown in the final test results in competitions with other professional rig builders across decades now. I've talked to Matthew up there off and on for 20 years, along with a couple of other guys, and (much like me) they'll segue off into fascinating trivia discussions at the least excuse -- in their case, about tests they've been doing to carefully maximize performance. They like to chat shop; not ONCE have they ever chatted shop as a way to upsell me on something,
ever. On the contrary, they've warned me off paying for various pieces of hardware, when I had questions about them, every single time I've contacted them personally for a quote (more than only for my own rigs). They don't encourage ordering any rig from them without carefully talking it out first, in person, often to DOWNQUOTE out unnecessary or trivially superior components.
So, no, I
don't know that the story about how they're able to configure and match the hardware like nobody else can, is crap. They're highly competitive professionals in a very niche and thin market going up against other highly competitive professionals, and all the evidence I've gotten from them in personal experience and from tech journalists comparing the merits of various rig designers (even when some of those occasionally edge out FNW on performance), points uniformly in the other direction.
More importantly, they're able to configure and match the hardware a damn sight better than
I can. So do plenty of people, all over the world!

But unlike any of those other people, FNW has earned my repeat business. Partly by not needing to repeat my business much with them at all.
That is
not an argument that Gus or anyone else should use them over any other option. I look forward to hearing about the merits of whatever builder Gus ends up using (if he doesn't end up building it himself).

This rig will be borne of four fathers. I am happy to say it’s the most research I have put into a rig purchase and even happier to say that I will be saving hundreds of dollars. Friday!!
I'm certainly glad to have been of any help.
