This thread is to show off your gaming rig with Linux.
I'll start:
CPU: AMD Ryzen 9 5950X - 3.4 GHz Processor - 16 cores
Motherboard: ASUS ROG STRIX B550-F GAMING - DDR4
RAM: Team Group ZEUS - 64GB: 2x32GB DDR4 RAM 3200MHz
GPU: Sapphire Pulse Radeon RX 7900 XTX videocard - 24GB GDDR6
SSD: Samsung 990 PRO Heatsink - 2TB SSD NVMe
Why not make it, show off your rig? 
The truckers will come from miles around...
Good job I didn't suggest "show off your thing". 
This is my kind of thread! 
CPU: Intel I-7 10870H 2.2 - 4.8 GHz 8-Core 16-Thread
Motherboard: MSI GE-76 MS-17K21
RAM: MSI - 32GB: 2x16GB DDR4 RAM 3200MHz
GPU: Nvidia RTX 3080 - 16GB GDDR6
SSD: Western Digital - 2TB 2x1TB NVME Drives internal
EXT SSD: Western Digital P40 2TB NVME
Then when you ask them if their rig has an APU, they will direct you to bellow their bunk, there's your APU right there, powers everything, except the kitchen sink.
When you ask them what powers the kitchen sink, they will respond with, gravity. 
Certainly not on the first date!

I havent tried cp2077 on the new system yet, is fsr4 supported?
Nice! Very nice indeed.
How's the CPU and GPU temperature on that beast?
Here's mine:
i7-12700K - a 12 core cpu
32 GB DDR5 RAM
XFX 7900 XTX - an AMD graphics card, I don't regret this change.
360mm CPU cooler that i recently switched to
Lets get it overwith, I'm ready for the windows 11 hate comments
(yes i am hating every moment of using windows 11)
@freshjeff You just won the award, 
for the prettiest PC. I love it so much, I wanna hug it. Im filled with warmth after seeing those pics. 
I don't really measure temps these days. I try to downclock the cpu and gpu as much as possible to avoid wafts of heat (until winter). I got the cpu stable at 4ghz 0.83v and -30% PL -80mv in w10. I only use w10 if theres absolutely no way to get a game to work (usually mods for old games) and for real pwsh developement. I still consider myself new to linux and dont really know how to downclock and undervolt.
122F in American units = 50C rest of the world units

I use an Afmat cooling pad, uses 2-blower fans, and has a silicone seal going around it, to force the air up into the notebook. It was one of the first things I got, when I got this computer.
I'm grateful I spent some money to get an notebook with an aluminum case, that heat transfer helps, as well as the cooling pad. I normally keep my computer at 2.2GHZ, fast enough for most usage, without creating excessive heat. When I'm gaming however, I generally run it at 3GHZ to 4GHZ depending on the game, and set cooling pad to full power.
In the words of the Mandalorian............
Your "Ultra Violet" rig photo's are nice, but "Infra Red" ones would show hot spots? 
I decided to splurge when I got a new job that actually paid well, otherwise this would be a much lesser system than I currently have. That being said, this is the first time I powered it on in months, so it doesn't see much use currently.
Machine: Type: Desktop Mobo: ASRock model: X570 Phantom Gaming 4
CPU: Info: 12-core model: AMD Ryzen 9 5900X bits: 64 type: MT MCP
OpenGL: renderer: AMD Radeon RX 7700 XT (radeonsi navi32 LLVM 19.1.7 DRM
I don't care for case mods or RGB, so mine aren't much to look at. I've got two that are currently up to my standards. (once again, the hyperactive forum censor complains about nothing and I rephrase...)
(I don't care for RGB but sometimes it's hard to avoid, and the case is opaque, so it's not worth working to exclude.)
The newer one I'd have to partially disassemble to take my own photo of. Using a stock photo of the model:
The newer one was midlife crisis foolishness. I didn't need to upgrade yet, shouldn't have, and regret the small form factor. It's cool looking, it's convenient to move around if I need to, but it's difficult to work on because the AIO is in the way, I can't use 360mm of AIO fans, and the small form factor motherboard only has two M.2 slots.
That's a beast of a machine mate. You must be happy with that.
I've been researching my own midlife crisis SFF gaming machine. But based on your experience I might hold off. Considering the older i get the less time i have for gaming. I might regret sinking $3000 into a sweet gaming machine that i then just use for Word processing and reading textbooks. Hahahaha.
It was quite a bit more than $3k, I regret to say. I do like the machine, honestly, but it has been a hassle. One of the AIO fans broke, I assume in transit, because Falcon Northwest does significant testing prior to shipping and documents the results. This lead to overheating in normal use. I also had a scuffing noise from the PSU, but only occasionally. I sent it back in for repair, and they did the AIO properly, but apparently no one heard the noise from the PSU.
When I got it back, I did after a couple of days, and they investigated further, finding that the Silverstone power supply had a logo on the grill that the fan could occasionally scuff. They sent me a replacement grill without the logo and guided me through field repair (necessary because getting at the PSU past the AIO was problematic), and it's been fine since, but if I really push the CPU via Folding@Home (much better way to burn electricity than AI will ever be), there's just not enough cooling, and it'll throttle.
For your situation, honestly whether an SFF is a good fit or not depends heavily on what you play and the hardware you'd put in it. I put the newest (at the time) CPU and GPU in in a much tighter space than a standard ATX mid tower, and I actually push them. That's GOING to get hot. If you don't tend toward demanding triple A games at 4k, you could aim closer to the $3k you cited, run cooler, and never have a problem unless you want to do upgrades yourself--in which case the tight space could be a hassle.
I built my first SFF computer this year as well. I'm finding out slowly, the smaller the form factor, the more external accessories I need to get. One of my buddies who is great with 3d design made me a 3d print of a bracket to hold HDD's in a gap that had no purpose left bt the case designers. I somewhat regret building SFF because I must work around, what I consider to be, poor design choices. In the back of my mind, I think about taking the computer to lan parties or friends houses, but I end up seeing it as wasting time (and potentially damaging components in transit) when I actually want to chat and catch up.
