1. Is this a gaming rig ? If so, what applications need the extra cores as opposed to a 9600k ? Saves ya R2750 ... and it's 5+% faster than the closest 32% more expensive Ryzen option
9900k = 101.8% for R7599 ... relative value (100 x % / cost)= 1.34
9600k - 100% for R4849 ... relative value = 2.06
Ryzen 2700X = 94.5% for R6399 ... relative value = 1.48
At 4k ....
9900k = 100.3% for R7599 ... relative value (100 x % / cost)= 1.32
9600k - 100% for R4849 ... relative value = 2.06
Ryzen 2700X = 99.8% for R6399 ... relative value = 1.56
At 1440p
9900k = 101.3 for R7599 ... relative value (100 x % / cost)= 1.33
9600k - 100% for R4849 ... relative value = 2.06
Ryzen 2700X = 97.2% for R6399 ... relative value = 1.52
If doing video editing, unless ya spending more than a third of your hours doing that. take # of cores out of consideration.
2. On the MoBo side, there's many things to consider.
BIOS and Manuals - Asus > MSI > Gigabyte
Support - MSI > Gigabyte > Asus / AsRock .. the last to seem to have adopted GFU approach.
Performance - Asus suffered a bit from Z87 thru Z170 but has since returned to form .... have to give MSI a slight edge but by the smallest of margins, then AsRock and overall Gigabyte. The Asus TUF series has been a lot more reliable for us than the RoG line.
Price - Everybody else and then Asus
My favorite MoBo right now in a reasonable price range is the MSI Z390 Gaming Pro Carbon
3. RAM - I recommend the most attractive to your taste pair of 2 x 8GB of DDR4-3000 CAD 15 or DDR4-3200 CAS 16
4. I concur with your GFX card selection ... it tested 2nd highest (144.5 fps) so far here on TPU in overclocking test (0.9 fps behind leader) and makes 0 noise at idle . If ya jump up to the 2090, than it came out 1st place in fps on TPU OC test (180.2 ... 5.2 fps over next closest competitor

5. Fro the options on the sistes you listed the SF leadex Gold is the best option to my eyes.
6. The Phanteks 600S is my pick for a the best quiet case with great air flow ... see hardware canucks review on youtube ... the the best case in the under $200 category , the Phanteks Evov X is stunning ... but it adds R430
7. For storage, I's start with a 500 GB M.2 SSD + a 2 TB SSHD (50% faster than a WD Black HD) in gaming
8. Cooler options are limited.... I can not recommend CLC type AIOs and the only open loop, all copper system they have is expensive at R6,276 and the only air coolers there of note are Phanteks ... if ya can find a Scythe Fuma, grab it

Seagate 2 TB SSHD -
R1,790
Phanteks PH-TC14PE -
R1,079
That totals
R35,219
Upgrades / Downgrades worth considering :
Upgrade to MSI Gaming X 2080 =
(+R5,000)
Downgrade to 9600k
= (-R2,7000)
Upgraded To Phanteks Evolv X
= (+R430)
If you do all 3 total is
R37,899
If you keep the 9900K for the extra 1%, it will be
40,649
Questions:
The HAF 932 was a great case ... 8 years ago... not today.
Does 1440p change the picks ... No. No but even the 2080 Ti is pushing it at 4k. To my eyes, the best gaming experience still is at 1440p w/ a 165 HZ 10 bit IPS panel from AUOptronics (turning G-Sync off and using ULMB instead) ... but that may cost more than ya would get from selling the existing 4k panel ... Acer XB271HU (10 bit) ... Asus PG279Q (8 bit)
How does Palit compare performance wise ? .... this is how they shook out in TPUs Max speed at max clock testing for the 2080s
