tl;dr Don't buy the Wraith Wripper TR4 or bequiet! Dark Rock Pro 4 TR4.
Noctua U14S is still your best bet unless you want to deal with an AIO for a workstation, which is highly not reccomended.

Nano XDR with pro stand. Also bought AppleCare+.  $9000 Canadian total sine I also bought the webcam. Loiteh Magneti Pro 4K 
see and jee key are not workin LOL

Came with some random crap on the screen but after I wiped it off with the 'special cloth' it's amazing.

Why are you trying to convince someone on a budget to drop $1000 on a chair?

I wouldn't use a 3080 with a 1080p 144hz

Seems like a weird combo to use a 3700X and a 1660 Super even more so with Zen 3 around the gate. I'd say 120 Fps? Maybe closer to 100
 

XG27UQ isn't such a special monitor, nothing about it is super noticeable. Make sure you're using DP and DSC enabled. What GPU do you have? It might be running with shitty colors
 
Anyways, whoever says they can't notice a difference between 4K and 1440p must have terrible eyesight. The difference is there but if you just want to game I'd stick with 1440p 144hz 

They are quiet but not really silent. 
If you have shitty hearing and claim everything is 'inaudible' maybe. I've heard people say their H100i / H150i is inaudible under full load with a 10700K. 
 
Keep them below 1200 RPM at max load and you'll be good.

They're probably annoyed from people asking

I've been wondering too since I dunno about their more technical ratings for something that's very preference oritented like headphones.

There isn't, if you're not going to play LoL or CS:GO competitively.
The fact that the 360hz costs the same is really a waste of time.
I would just grab the G7 or even a 27GN950 and call it a day.....
 
$700 for a 1080p display is nuts.

That's horrible. 

That's horrible. 

What currency are you talking in? USD is not the same as say AUD or CAD.

$200 980 Ti is not really a good deal anymore. Get a 1070.
However $70 for a 980 Ti on EVGA's B-Stock store is quite good. I'd get that instead, if you can checkout before the bots.
The PSU may or may not work.

I only use mine for gaming. 
I would not use it as a desktop monitor since burn-in is inevitable. 

Zen 3 desktop parts will be releasing in COtober.
Just wait.....
 
4790K is worth about $100

Note: B550 support PCIe Gen 4 SSDs.
850W is plenty since the 3900X isn't really a power hog.
I would go with a PCIe Gen 4 drive since I don't think you would benefit from a 5000 Mb/s drive.
Case - I'd go with a P500A/Lancool II Mesh. Define 7 if you want to use a bunch of drives.
 
Doesn't seem like your needs are super demanding. Will 3080 be necessary? 

Your eGPU will not let you use the 2080 Ti properly.....
It's technically PCIe Gen 3 x4 bandwith.

They don't exist for LGA1200.
You're looking at HEDT. Why do you need to upgrade from your 9900KF? It seems more than enough for gaming, really.
8 DIMMs is quite difficult to run as well.

It shouldn't be. Besides nitrogen, the vast majority of the balance is oxygen and argon, neither of which is flammable. If you're talking about the canned stuff, it's the propellant that's flammable.
1,1-difluoroethane is a common one.
