Cooling cooling cooling.
Things I've never had to do before:
Add up the wattage of all my components.
Downgrade a processor from the one I wanted due to wattage and heat
Carefully consider my airflow design, since liquid cooling won't work ideally in my case
Measure the height above my CPU to find a good enough heat sink.
Downgrade from my preferred video card so my machine doesn't actually catch fire.
Consider the distance between my PCIe slots.
Gosh, they are really pushing the envelope in terms of power and thermal properties of newer computer designs.
You have to pick your case, fans, sinks, PSU, CPU, and everything super carefully.
I hope I built in enough headroom because I'd hate to find out that one day my little cube of computer power turned into an expensive furnace full of slag.

Sounds like you are confined to a small encloser. I just built a new rig and had to measure if my heatsink would fit. I'm working with a mini ITX case, it's entire front is a 20cm fan, cooling isn't a problem. I'm not going to advertise it but "Thermaltake mini itx case" should find it.
Why do you need that gpu you have? Are you using your dev box as a game machine?

Edit: My preferred would be a 4090 but for fire hazard and cooling issues. I like to build 10 year systems, and a 4090 is by best shot at that.
The 2080 TI GPU i bought because i basically stole it for that price. I figured if I didn't use it I could resell it and easily more than double my money.
I just got a 3070 TI for free tonight too. Didn't even have to pay for shipping.
I do use the 2080 TI to play Fallout 4, which I play to scratch my game development itch (the game engine allows you to customize and otherwise modify it until it's an entirely different game)
But primarily, it's a development machine. The GPU is a luxury.
I don't mind developing and gaming on it because everything I do is in source control.

Probably off topic but as you know I'm a Windows guy. The dev box was for experimenting with SerenityOS.. I'm super impressed with how much horsepower you can pack into these mini-ITX cases. I used an AMD APU, no need for a gpu.
Don't try to combine a gaming machine and a Dev box, what a ridiculous idea.

Don't think of it as a gaming machine. Think of it as a dev machine i occasionally let distract me.
I actually don't have room for two PCs in my space.

I've got 13 of these little ITX cases stacked in two columns, on top my desk [6,7], and I love them.

I want single core performance and a RAID 1 NVMe setup on my dev machine from now on. I'm playing for keeps. Compiling lots of little files every time i have to rebuild is getting in the way of my productivity. It will pay for itself easily.
You can't really do that on an ITX machine. You have cooling issues unless you go total open air and even then you can't really get the higher end CPUs to run on those without cooking.
Even my MicroATX case won't handle a 13th gen high end i7 or i9. They run at 250W. My power supply can handle it, but if I didn't melt the CPU i'd melt the mobo.
Then there's my 4x NVMe RAID enclosure. I can't use onboard RAID because I want 3 sticks to saturate my PCIe 3.0 x16 bus and I also don't want to RAID my system drive. And the enclosure is as tall as a video card, and needs cooling.
And the GPU. My GPU requires at least a 600W power supply minimum, 700W or better recommended. That alone should tell you how it feels about ITX setups.
The bottom line is after looking, ITX won't get me what i want either from a gaming rig, or a dev machine. not yet.

Worked for me.
Not that the GPU gets used a lot during coding, but it's not in the way either. VS works perfectly fine on a gaming machine. There's also a server here, in the living room and having two desktops on two writing desks in the living might be a bit much for her. There's also a server here, running 24 hrs/w.

Even if you keep the core of the system for a decade, improvements in perf/watt on the GPU are high enough that you'd probably come out ahead at the ~5 year mark buying the same level of performance @ 80% lower power. Unless you want your gaming performance to decline from god-tier to potato over your system lifetime you'll need at least one, probably two GPU swapouts at similar performance tiers as the original card.

I only really play Fallout 4, though I mod it to the point where it strains my 2080 TI
I will continue to play Fallout 4 until Fallout 5 comes out. At this rate I will probably be dead or blind by the time Fallout 6 launches. 
A 4090 should do it for me, I think. Though on reflection, a 3090 TI is a safer bet for my system and I could always swap it out later.

Agree.
Been there done that, several years ago, when high performance GPU's showed up.
Not sure when water cooled systems came to be the need,
but if one does not have that option, pump air through an open air chassis as much as possible.
External fans an option.

My chassis can take liquid but I don't want it because it is open air. The way the radiator mounts in it, I'd be wondering if the positive air pressure was flowing out all the gaps in order to keep the pet hair and dust out. Right now it works perfectly with 4 120mm fans 1cm away from the top glass panel. It pushes the air against the glass, causing it to flow out toward the edges in all directions and push air out those gaps.
The case is a Thermaltake Level 20 VT. It's by far the nicest, best engineered case I've ever owned. The airflow was thought out very carefully, at least for air cooling, which is what I'm doing, and plan to continue.

Have you thought of trying liquid air cooling?

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.

The Cray-2 approach...

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.
