"Featured-items" is just marketing-speak for the products they make highest margin on, or the products they have excess of in stock and need to clear before they become too obsolete to sell. So be wary of those IMO.

Yes, I kind of figured that out. Seems like you better remember to change the criteria to best-rated FWIW after each selection.

Gpu power cabling is adequate for a GTX1070 or RX480, plus PCIe-powered gpus can be included (GTX1050Ti, RX550)

However my search of Newegg or ibuypower fails to find any motherboards housing more than 1 CPU or 128 GB of memory.

Anywho I am considering a Ryzen 32-Threads@16-cores for now.

Yes, there are certainly motherboards that will handle 2 CPUs, and a few that can take 2TB. For example, Gigabyte MZ72-HB0 will let you pop in a pair of EPYC 7002-series CPUs, perhaps the EPYC 7H12 with 64c/128t. Then just drop in 8x128GB RAM and you're set, 128 cores (256 threads) and 2TB of RAM.

That said, I'm not sure if this is the budget range you're looking for. At a quick calculation I'm seeing ~$9000 per CPU, $1400 per RDIMM so that's about $30k just for CPUs+RAM. Figure in another $10k for all the other neat bits (PSU, case, taxes, etc).

Thank you for the insights and links. Equivalent of 64 x quad computers in a box. That's what dreams are made of.
Unfortunately the reality of not being able to afford dreams is the story of my life.
I already went way over my head with a single Ryzen 9 and 128GB of RAM.
Received the parts on Monday and my 1st build ever is almost complete.
It powers up and I can see the BIOS.
Have to close the case and setup the software.

Congrats! Your build is quite powerful, and with the megacore socket CPUs currently available there isn't much reward for the expense of two-socket machines for the work you do. 128GB ram opens lots of interesting possibilities, for ECM or matrix-solving. :)

Most of us can't afford our dreams. That's why they're dreams.

I will be doing like you and building a new system at the end of this year (as my current system passes the 9-year mark). I'll probably go with the 4950X (or whatever they call the top Ryzen), but am also waiting to see what interesting things the next Threadripper can offer for the price difference. And (no less than) 128GB, which seems like a mediocre upgrade considering I've had 64GB for 9 years.

What parts did you use?

Have you seen this thread?

Thank you very much VBCurtis. I did try to get my feet wet with ECM, but the math is beyond my linearly wired mind. On the last check, all the off the shelf software are Linux based.
My environment of choice is WinThose. Plan to install Ubuntu on the new build. Will see how things go.
Thanks again.

Absolutely. It was the push I needed to go ahead with my 1st build. My strategy for choosing parts was brilliant. Use the Newegg PC builder and choose components with highest rating and least prices with the "Ships from Canada" box checked. Seems to have paid off so far. I will post a picture of the box when it's done. The only mechanically idiotic design features I encountered were the ryzen heat-sink/cooler bracket (think I aged couple of years before it mounted) and SATA power/data buses elbowing in opposite directions. Everything else just snaps in place.

And here is my new best friend.

There is a slight Major-Design-Flaw/Outside-the-Box-Thinking (Depending on how you look at it).

The case PSU is housed in the bottom of the box >> Install PSU right-side up >> Very small PSU air flow clearance below the box on hard floor >> 0 PSU air flow clearance below the box on carpeting

or

The case PSU is housed in the bottom of the box >> Install PSU Upside-Down >> PSU sucks in hot air from inside the box like a regularly configured computer-case >> Losing sleep for installing the PSU upside down

So far I have opted for the former configuration. I figure might as well order spare PSU's since they will not last long with no air flow.
