Its my first build im a bit nervous about everything not working :)

What you have will work.

But... I have some thoughts:

1. Liquid cooling is no more effective in a good case like yours than air cooling.
I suggest a scythe kotetsu for $35.
Here is a review:

See my liquid cooling rant at the end.

2. Ram is fine, I like lpx. If 2400 speed is cheaper, buy it.
There is little benefit from 3000 speed overclocked ram.

3. 120gb is too small for a ssd these days. 240gb at least.
If you can buy 500gb, defer on the hard drive until you actually need the space.
Today, I would only buy Samsung evo for performance and reliability.
Also, WD is better for hard drive reliability.

4. 450w is fine for GTX1060.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
That evga psu is not one of their best.
I would look for a Seasonic S12II 520/620w unit which is a tier 2 unit on this list:

5. Love the i5-7600K for gaming.
As of 1/13/17
What percent of samples can get an overclock
at a vcore around 1.4v.
I5-7600K
5.1 28%
5.0 52%
4.9 72%

My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
And... I have read too many tales of woe when a liquid cooler leaks.
google "H100 leak"
I would support an AIO cooler only in a space restricted case.

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
