2-3 front intake and 1 rear exhaust would be plenty already. It would also get past the horizontal mounting issue.
2x NF-A14 front intake: http://www.nanokatalog.com/urun/nf-a14-pwm-ch-bk-s
1x NF-S12A: rear exhaust: http://www.nanokatalog.com/Noctua-NF-S12A-PWM-120mm-1200-RPM-18dB-Kasa-Fani,PR-102286.html
 
If you want to save some money, here are cheaper alternatives:
TY-141 for front intake: http://www.nanokatalog.com/Thermalright-TY-141-SV-152x140mm-Kasa-Fani,PR-103124.html
PW2 for rear exhaust: http://www.nanokatalog.com/be-quiet-Pure-Wings-2-120mm-1500-RPM-192dB-Kasa-Fani,PR-98966.html

I would suggest to return the AIO you won't find a bracket for it as the ones from NZXT and Corsair are designed for Astek type coolers. 

580 would be the best option, depending on the prices you can pick one up for.

If you're not planning to oc, a PR Slim should be plenty: https://www.amazon.com/quiet-BK008-Pure-Rock-Slim/dp/B01KVNCEIG/ref=sr_1_8?s=pc&ie=UTF8&qid=1523420752&sr=1-8&keywords=am4+cooler&refinements=p_n_shipping_option-bin%3A3242350011
If you want a bit more cooling, the Viper is better albeit not as quiet: https://www.hepsiburada.com/akasa-venom-775-1155-1156-1150-1151-am2-am2-am3-am3-uyumlu-islemci-sogutucusu-ak-ccx-4002hp-p-BD100258?magaza=Teknobiyotik
It might be a good idea to contact the seller to see if it includes the AMD mounting lever though. Half of the cooler's reviews mention it as included and another half gives it no mention. 
What shops are you looking at? I'm having a bit of trouble finding the Turkish shops I used to browse.

The Viper fan is noisy at high or max rpm but most fans are. It can be lowered to ~600rpm where it should be fairly quiet. 
Why not a 92mm fan? The PR Slim is quieter and performs similarly to the Freezer 33. 
The Pure Rock with a 120mm fan performs similarly to the PR Slim but is a bit quieter at load. 
If you want to oc, a beefier cooler like the the Mugen 5 Rev. B would be good: https://www.amazon.com/Mugen-Rev-CPU-Cooler-Support/dp/B06ZYB8K77/ref=sr_1_4?s=electronics&ie=UTF8&qid=1523476637&sr=1-4&keywords=scythe+cooler

Get a Gammaxx 400. They're pretty quiet, look good, do an excellent job of cooling, better than many coolers that cost twice as much, are compatible with Ryzen right out of the box and cost around $20 (US).

Well I have the cpu above yours (r5 1600x) and it doesn't come with a cooler. I bought a cooler master hyper t4. It's not easy to mount. You do need 2 people but it works just fine.

Your components wont go hot in a Define C or R5 especially if you've got fans in a lot of positions like you plan on doing. Fractal Design knows how to balance noise and airflow
 
Seeing those prices, I'd either go with the Define C, 460x (since it seems to be on sale) or the RL06. RL06 will have the best airflow, 460x will look the best, and Define C will be the quietest and smallest, possibly also easiest to build in as well.  

Here's a good example. Nearly identical case too (just slightly longer)
 

Define C. Having TG is nice, but the Define C is a much more quality case everywhere else. The Define C does have a TG option (if you can find it in turkey), but it might put it out of "competitive range" of the View 21 TG

Fractal Design Define R6 is a great choice with lots of options - especially if you're air cooling.

Well I went with the i7 8700 locked because:
 
It is cheaper, it does not need to be delidded, it is much cooler to where the Hyper 212X keeps it super cool while being super silent, you're not overclocking so you can cheap up on motherboard and grab just about the cheapest z370 you can find (still good for memory overclocking) and on top of all that for the very first time Intel has made the locked i7 IDENTICAL in performance to the unlocked i7, both CPUs have an all core turbo boost of 4.3ghz making them essentially identical at stock settings, meaning you only start getting more performance after overclocking you get none out of the box.
 
And to overclock you need to spend lots as mentioned above.
 
To me it was a no brainier cheap up hell lot going with the locked i7 8700 and I have pretty much identical experience of the i7 8700k 5GHZ specially in gaming which is more and more GPU bound.
 
Adding the GPU price spike up I managed to replace my 1080 Ti for the TITAN Xp at no expenses and I can assure you the i7 8700 is not bottlenecking my Xp at all.

That is really not the best way. Make your front fans intake and rear and top ones as exhaust. Basically use your AIO fans as intake and top, rear fans as exhaust.

That's just Ryzen as a whole though. My B350 Strix still can't run Hynix 3200 MHz memory above 3066 MHz. That's also a problem with AMD using an IMC on the CPU, which means that that it's own silicon lottery right there.

Honestly, now is such a terrible time to build a PC it's ridiculous. Memory is expensive. GPUs are practically nonexistent. Intel's i7 is nearly 400 dollars. Cases, by and large, have zero airflow.

You are using DDR4 RAM's. Double Data Rate. So double the number you see in programs like CPU-Z and got the actual speed.

It should, it should bleed to the other side. Not 100% sure since I've not seen many people with the frames in a PC build
 

Its also not a good idea to download files from suspicious forum users with 3 posts. Meltdown inc right there...

Yeah totally just upgrade. M.2 Seems like a good idea, you should get one and install OS on it. other than that you can't have enough RGB, I've been using the NZXT hue for 6 months+ and I can recommend it. I can also recommend a 1080 ti and a 4K monitor, though you should get one with a decent IPS or OLED panel. an another option is 1440p 60 or 1440p 144hz.

think the X62 is a little better, doubt its a lot and its almost certainly noiseier

Yes i was thinking like that. Phanteks cases are just amazing. I will go with a Pro M.

@TVwazhere that radiators thickness is same as the x62. Also the fan thickness is standart and same too. If it can be fitted with a TUF motherboard I think it can fit with my motherboard too. Thanks. I think I will go with Pro M if I don't find a better case which I don't think I will find.

If you are a normal PC gamer then the effect for you is very very low. You don't need to worry about it. The main problem is the servers because the problem is with the cache. If you are a normal PC gamer don't worry.
