I did briefly consider submerging the entire thing in a mineral oil bath and cooling it with a box fan. 
Or liquid nitrogen, but that gets messy and i have pets. It could end poorly.

Has anyone ever made a Cray-2 simulator running on a modern PC? I'd be curious to know how the hardware 1985 Cray-2 would compare to an emulator on a top-range gaming PC of 2022!
I suspect that the result might be like my Alma Mater's Cray-1: After a few years it was thrown out - its processing speed was certainly high enough, but for the major tasks - weather forecasting and FEM - the volume of the raw data to be processed was so immense (for the day) that the CPU was idling, waiting for the input channels to fill up memory. The Cray-1 was replaced by a Cray-2; apparently, the Cray-2 I/O-capacity was a lot higher. I wouldn't be surprised if a modern CPU/GPU can compete in processing power, but given similar weather forecasting / FEM tasks, the bottleneck would be the I/O, just like the Cray-1.
Yes, there are datacenter-oriented versions of the top chips, with loads of PCIe lanes. They would probably come out better than the gaming-oriented chips.

I think unless you want to go full-on liquid cooling, you'll need to compromise.
From what I understand, you don't need the 4090; just get a 30xx series card (maybe a ti one) and get the best air cooling solution you can get (double tower cooler) and add RGB fans, because everything is cooler with RGB.
If the usual ambient air temperature is relatively cool, it should be good enough (don't trust me here, I have no clue)
But what I can see, most people recommend an AIO for the i9 series cpu.

I'm not going liquid because my Thermaltake Level 20, while it supports liquid, is an open air chassis design. The glass front and top are air gapped from the chassis. Because of this I need positive air pressure along the top of the case. Currently I have 4 120mm fans about 1cm away from the glass, pushing against it, causing the air to flow to the edges of the glass and produce positive pressure around the case's air gaps. With liquid, I have to remove those fans to fit the radiator, and between that and my video card, all the air will flow out of the left side of my case only.
It's not so much a cooling issue, the airflow. It's a cat hair issue.
So I stepped down to an i5-13600K since it runs at just over 180 watts instead of 250.
I've heard the 4080 and the 3090 TI have the same power draw, so I may get a 4080. I heard underclocking them they are super efficient (performance per power draw) at 300 watts
Here's my new target specs
PSU: EVGA Platinum 1000 watt
Mobo: ASUS/ROG STRIX 690z G Gaming Wifi
CPU: I5-13600K
RAM: 64GB Corsair Dominator
GPU: 2080 TI though I'm probably upgrading to a 3090TI or 4080
Storage: 2TB Samsung 990 Pro NVMe system drive. 3x1TB RAID 1 Samsung 990 Pro, for 20 Gigabyte a second reads (I think?) for secondary fast storage
Chassis: Thermaltake Level 20 VT

> I think unless you want to go full-on liquid cooling, you'll need to compromise.
These days you can just get a standard AIO system for CPUs (Corsair H150 and co) and be done with it. Far less effort than going all-out, and not really an issue unless you want to start overclocking.

I would get an AMD processor. They have a new series coming that will not have the X suffix and will use about 65W. That should be rather easy to keep cool. Rumor: AMD Ryzen 7900/7700/7600 non-X specifications + pricing revealed, release date of Q1 2023.[^]
You can also down-clock GPUs and reduce the heat they emit. The site linked to also reviews video cards so they have a lot of info on those too.

I'm after maximum single core performance, and no 65W processor will net me that, much less an AMD which is better at multithreading than single threading in terms of efficiency and performance.
I'm on a Ryzen 7 4750G right now.
I've considered getting a 4080 and underclocking it, because it's super efficient at 300W but right now I have a 2080 TI and it works great.

Note: I have to go with the i9 spec in that review because it doesn't have my i5, but single core perf is close to the same on both.
After reading that review I'm still going with the intel, as it outperforms the Ryzen on GCC benchmarks, and some other single core heavy tasks - i'm guessing a lot of it has to do with having more on die cache.
This is about compile times with GCC, so anything that bests it is my go to.
The other thing is the 13th gen are new, and they haven't filled out the model line, so I may have some upgrade paths in the future. The Ryzen is a little older, and where it sits in the AMD lineup it's probably near their top end for that generation of chip. I think. I know a lot more about intel's habits in terms of chip development, their tick/tock cycles, etc.

I currently have a 5950X at work and it writes to an NVME drive and build times are lightning fast. I use VS22 with about 100 or so projects and it is really quick.
Have Fun.

I've come to appreciate having a tiny box on my desk, so these days I have a NUC sitting right next to me, but RDP into my big rig, which generates a lot of heat, is loud, big, and--most importantly--in another room, so it doesn't bother me at all.
I have 3 monitors connected to the NUC, including one running at 4K - it's got plenty of horsepower for that.

I switched over to a single 55" 4k QLED smart TV as my monitor. I hate multimon for many reasons.
My PC is a relatively small cubish thing. A Thermaltake Level 20 VT. Dimension (H x W x D) 348 x 330 x 430 mm (13.7 x 13 x 16.9 inch) - 2 and a half pill bottles tall, for perspective (don't ask )
My PC isn't very loud, even on air, unless I'm pushing the GPU, and currently I'm not anywhere close to having heat issues, because the system is fairly modest compared to my target upgrade.

Right...I was merely making the suggestion to build a beefy system but put it in another room (so the heat/noise isn't an issue for where you work), and then just RDP into it. I've been doing that for a few years now, and I wouldn't allow a loud PC back into my office.

I think I read a day or two ago that you want to stick with ITX. Why is that? Seems to me that limits your options.

No. I'm avoiding ITX. My chassis fits MicroATX.

This makes me feel better.
I've been buying the Precision Laptop/Workstations.
They are gamer designs I use for development. I don't play any games, so I sacrifice the GPU a bit.
(as long as I can run 4 monitors, or one 55inch 4k UHD, I am good).
BUT... That said... We've seen overheating issues. I could leave my old machine running for days.
Now I power off every night.
I also have a piece of wood UNDER the back of the machine to increase airflow. One of my devs has his sitting on a laptop cooler (5 fan design) as he doesn't have the A/C options, and the summer months are a problem.
I've noticed it's only getting worse.
FWIW, I agree with building machines for long-term. I shoot for 5yrs. After 2yrs, I usually buy a "cold spare" (A used version of the same computer, off-lease), and use it for testing/validating my backups (cloned drives).
I can't fathom getting 10yrs from a machine. Hardware (specifically USB seems to fail before that time).
But the cost of a new machine is on par with the 80 hrs it takes to move my licenses to it. In the last 2 builds, I've slowly started using more VMs for various development environments. I am hoping to get this down to 40hrs. The part I truly hate is LICENSED software tied to the DRIVE_ID (Quickbooks). So if I upgrade my hardrive, the software doesn't work until I jump through some hoops. But I have like 4 of those. It's just adding time to the process...
Finally comment on heat. One of the devs who was NOT cooling his machine ran into NVME issues where the drives were getting too hot and faulting. He actually assumed the drive was bad, and went through the restore process (swapping back to the previously cloned drive, and then restoring from backup any changed files).
The next day, he checked the the drive he replaced, and it was working fine! Scary.
I read somewhere that some building in iceland/greenland uses BTC miners to heat the building.
Basically the BTC is a wash for the energy consumption, and the heat is now beneficial. Probably the most expensive heater ever built. (Not sure it's a true store or it was a plan, FWIW).
But I feel your heated pain!

I should have written that I shoot for 10 years. Realistically I end up replacing or upgrading components along the way, like adding more RAM, or an NVMe (although in this case I'm starting with NVMe sys drive, and RAID 1 NVMe x3 secondary storage so I can't get much faster than that with current tech. I designed it such that my read speeds off secondary storage will saturate my PCIe 3.0 bus.

This is why I built a Ryzen 5950x system. Best performance per watt. I am hoping power consumption will come down again before I need the next upgrade.

I'm looking for the best single core performance I can keep properly cooled, not the most efficient.
My i5 CPU slightly bests a 9xxx ryzen 7 on GCC benchmarks.

Always use the largest tower-case you can find that will work.
Not only will it provide a better aerated machine but make it much easier to work when building or maintaining the machine...

Nope. Towers mount the mobo vertical and thus suffer GPU sag. Also my thermaltake open-air chassis is quite good at cooling, and can fit a 4090 video card if I wanted to.
Towers waste space anyway. My little glass cube doubles as a shelf. =)

My son ordered a new high performance tower with liquid cooling for the CPU for game development, and I had to buy him a room air conditioner for it.

You will also need to renegotiate your terms-and-conditions with your energy company... unless you have your own power plant.
