Exactly who would pay for this crazy build? And why?

Are there any games that can utilitize 4 x 4090? What else?

Is this a one-off, or is this company planning to sell this build, presumably build-to-order?

Inquiring minds want to know.

Why would you want 4 cards? Unless you're into specific rendering or modelling 3 of them will be sitting with their thumbs up their arse...figuratively speaking that is.

Re: "what for?"
Machine Learning and rendering. People are definitely using systems like this for productivity, content creation, and research stuff.

There's someone on this board, don't recall username rn, who has been building systems like this since the olde 2cpu.com days for doing Actual Work. Last I saw he was running dual Xeons and multiple 3090Ti in a highly-modified TT P3.

Workstation Stuff these days can often use as many GPUs as one can throw at it, especially any "AI" type thing.

Id be surprised if it gets used for more than porn and pong. :p

In theory...

A dual GPU system would be useful for 4K 1000fps 1000Hz Unreal Engine 5.1 with 1ms latency via retroactive reprojection-based frame generation that reduces input lag.

Custom software.
Feeding one GPU with UE 5.1 outputting 100fps
Feeding other GPU with frame results and Z-buffer results, as well as 6dof reprojection coordinates, to do the VR-style reprojection algorithm, at 10:1 frame generation.

This is existing VR tech, and was recently in a LinusTechTips YouTube too, and written about in a 2018 article, "Frame Rate Amplification Technologies". DLSS 2.0 and 3.0 only increases frame rate 2-4x. The goal is 10x!

This would require custom software, though.

You know that thing runs relatively quiet, except for that tiny northbridge fan that sounds like a mosquito. That would make me return it. :p

Don't understand why that is $26000. Didn't fill up all ram slots when that CPU is 8 channel. Using a 512 gb Samsung PM9A1 NVMe as the only storage also? That is probably around $16k

Who's prices you basing that off of? The USA? I think their located some where in Asia, so prices could be a lot hire.

Just checked it. There from South Korea and this is cheap. They have another one for $37,977.70. So it seems we go it made in the good old US of A. Cheap in the USA.

Lots of CUDA applications around. In addition to machine learning there is molecular modeling and fluid dynamics just to name a few.

What I don't get is what application you have that requires both a high CPU core count and multiple GPUs. A 13900 should be enough to feed the GPUs, compile the software etc.

Nice system choice BUT thermal capacity is WAY under for 24/7/365 full load! I used to build systems like this based on the SR-2 fully spec'd out and the baseline was FOUR MORA rads and several liters of receiver/sump capacity and much more pump power. I like to keep the fluid temp within 1 degree C of ambient AND be quiet at the same time. It's not that design won't work, it's just going to have thermals and acoustics out of our design range.

Once you go big/quiet, you never go back LOL!

As far as use, I'm sure it's fine for games.
Just as my 96GB M2 Max Macbook can multitask like the devil. I'm talking watching a 4K Youtube video AND playing poker. At the same time! Yeah baby! 🙃

On newegg.com
CPU: $6400
motherboard: $1000
PSU: $450 * 2?
GPU: 2,200*4

Thats already $17,100, add 128 gb of ECC ram, little hard drive, nice big case and all the watercooling parts and you maybe get above $18-18.5k, $16K would be an extremelly good price

I was pretty close just calculating in my head! I knew I was a little under.

A system like that would probably have at least 512GB to 1TB RAM, 20+ TB storage and some fast SSDs even xpoint stuff. That's when it gets expensive.
And if faster networking is needed price out 40 or 100Gbps hardware and a 100TB RAM SAN rack! $28k is probably a minimum downpayment for the financing. ;-)

From what I've heard from weirdos who do work on their computers, a lot of the storage is on a separate server and they just need an SSD for local file manipulation. Checking the website and converting 28,800,800 won to USD gets me ~$22k, so not too bad I guess if you're not willing to build something like that yourself and want support. Builds of similar workstations from major companies are way more from what I've seen (For example: https://shop.lambdalabs.com/gpu-workstations/vector/customize), and I like the watercooling aspect of this since I'm assuming it keeps noise somewhat tolerable.
