I've had EK's Ekoolant in my system for about a year now and so far so good. No problems with it at all.

People also use distilled water with anti corrosives and anti microbial additives. I like clear coolants to prevent any kind of gunk or color build up in the blocks or radiators. I've only ever used EK coolant but other people have had luck with primochill coolants and mayhems as well. 

You shouldn't need a fan at the rear honestly. Three fans if they're any good will give your components enough airflow.

I would leave all 3 in the front.

Does it come like an AIO? Or is it just a water block?

Corsair is never a bad choice, but any 2x 120mm or 2x 140mm cooler that has good reviews and you like the look of will handle overclocking of that CPU just fine.
 
That being said, you could look at the EK Predator. Its an expandable AIO so if you ever wanted to add another radiator and a gpu to the loop, you can, and it's under 200 for the 240mm model.

Founders edition is definitely not worth it. For the premium you pay plus the price of the waterblock, you could get a MSI Seahawk EK or EVGA Hydrocopper version of the card with a waterblock already installed.

The EVGA ACX 3.0 versions (Stock and Superclocked) uses the reference board layout, making them compatible with the normal waterblocks. The FTW, Hybrid, Hydro Copper, and the Classified/K|NGP|N versions requires a special waterblock design for those cards in order to work properly.
 
This is the reference layout for the GeForce GTX 1080. Board layouts will vary depending on brand and model. I chose EVGA to demonstrate this.

On topic: I much prefer the lower price tag and the better cooling of the ACX 3.0 version. I can easily overclock just as good as the Founders Edition and get better temps at the end of the day. The Founders Edition is not a good investment IMO...

the bus won't limit you, but you cpu will limit you in some games.

I would get a i5 and a 1070 and get a norm ssd not m.2

3gb of vram is not going to be enough for battlefield 1 at max settings at that resolution, so a second 780 isn't going to help. My 2 780 ti's are limited by vram now which sucks.

I didn't realize you already have the 970, use that and get a z170 mobo, 16 GB of ram and an SSD. You won't be maxing out every game coming out atm, but you'll still have good quality graphics and you can save up for the gpu upgrade later and have a better build as well

You might have to repost the links

I would go with the first build because of the overclocking capable board because the board on the second build would have to be upgraded to fully utilize the overclocking potential on the unlocked i5. If you already have the 970, I would hold off on upgrading the graphics card because you're going to be spending $300 on very little improvement.

This is the finished product
 

Looks really nice gj.

I've been using the mouse for a while now and it's definitely the best mouse I've owned.

I would just keep it and upgrade when they come out with a bigger pascal chip if you feel that you need more performance at that time.

I like the longer videos. It shows more of the process of how ideas and parts come together. 

nf-a14 ftw

lenth is much more important

Not really worth it, that's why I use long slim rads. Fans can run slower and quieter. It really depends on the clearance in your case, if you can fit a slightly thicker rad it might help with a degree or two.

intel NUC? its easy to build, unscrew 4 screws, add ram and hdd, screw it back and done

You could try plugging the second monitor on the integrated graphics if you have that. Otherwise you could get a cheap gpu and it would work too.
