Generally buying two memory kits is less desirable than getting a single four stick kit. Memory kits contain electrically matched module so that multiple channel operation is guaranteed. If one mixes up the modules in two kits, (even though they have identical part numbers), there is a small chance dual channel operation will not occur. Also XMP profiles are based on the modules in a kit so using two kits may require manual memory timing adjustments.

both of them seem to be solid monitors, shouldn't go wrong with either.

Otherwise good build but your PSU is way overkill and expensive.

i'll be honest, very much overkill cpu. for just streaming a 3700x will be more than enough. but if budget isn't an issue, go ahead with the 3900x. everything else honestly seems pretty good, nothing really needed to change

i mean... many know my preference for air coolers, which would easily do with a dual tower, you have no pump noise, it doesn't block airflow and it costs half the price
 
I'd personally take something like a nhd15 or dark rock pro 4 over it

That motherboard only has 3 M.2 slots, not 4 like you mention.  You'll be fine tho.
 
WD goes in the M2.1 slot (since that one supports SATA), and the others go into the other slots.
 
Storage Devices
SATA 6Gb/s 8 x SATA3 6.0Gb/s Connectors, support RAID, NCQ, AHCI and Hot Plug M.2 1 x Hyper M.2 Socket (M2_1), supports M Key type 2242/2260/2280 M.2 SATA3 6.0Gb/s module and M.2 PCI Express module up to Gen4 x4 (64Gb/s) (with Matisse) or Gen3 x4 (32Gb/s) (with Pinnacle Ridge and Picasso)*
1 x Hyper M.2 Socket (M2_2), supports M Key type 2260/2280 M.2 PCI Express module up to Gen4 x4 (64Gb/s)*
1 x Hyper M.2 Socket (M2_3), supports M Key type 2230/2242/2260/2280/22110 M.2 SATA3 6.0Gb/s module and M.2 PCI Express module up to Gen4 x4 (64Gb/s)*

* If M2_3 is occupied, PCIE5 slot will be disabled
* Supports NVMe SSD as boot disks
* Supports ASRock U.2 Kit

Don't bother with Samsung SSDs, they're overpriced and the competition has caught up in performance. The MX500 performs just as well as the 860 and is $30 cheaper. The SX8200 trades blows with the 970 Evo Plus and is $70 cheaper ($100 cheaper, but idk how much longer this sale will last).
 
EDIT:
Your motherboard has 3 m.2 slots, you could ditch the SATA SSD altogether and go with two 1TB SX8200 and still save some cash.

Hello,
 
For gaming/streaming you don't need 64GB of RAM, 16GB is enough. You don't need that thermal paste, because I'm pretty sure there's some that comes with the AIO Cooler. 
 
IMO Toshiba hard drives are crap (I've seen a lot of them fail), go with Western Digital or Seagate instead. 

save you money, get yourself a good aircooler instead. its just as good and you dont have to worry about pump breaking or leaks. 
 
get something else. while the VRM is good, its not all that impressive, and you can get nicer boards around the same price.

say something like this

With what he was stating with his decreased performance and increased startup times of his PC due to the CPU being used 100%, i think it's time to retire the old devils canyon chip in 2019 for something more powerful. 

What's it for? Workstation?

You'll be find pairing a RTX 2070 with a I5 9600K.

For 1080p it is still good, above that you are correct 

I’d get a TUF X570, those are quite nice for X570.

you can update the bios without a cpu if it has a button for bios flashing, you can see whether it has it or not on the manifacturer's site

the psu is fine because you had it for only 3 year
 
I'd personally swap it to a prime-p, buy cheaper ram and keep it on the 3700x

Either it will bottleneck the bottleneck so hard that the bottleneck gets bottlenecked, or it will work just fine. 
 
It depends on how you use it... 
 
But IMHO as long as you go above 4 ghz with the I5 you shouldn't have much issues... but yes the cpu will bottleneck the gfx card due to it being at near 2080 level of performance.
 
But even an I7 or I9 will bottleneck... so personally when building a new rig I too would go for an I5 but not a 2070, only a 2060 if... ok I only run 1080p so that will be enough.
