No need for liquid cooling.
Use a noctua NH-U14s at half the price.
See my rant on liquid cooling at the end.
If you are overclocking, here is what to expect:
As of 1/13/17
What percent can get an overclock at a somewhat sane 1.4v Vcore.
I7-7700K
4.9 74%
5.0 56%
5.1 26%
5.2 5%
You will run out of safe vcore before you run into thermal limits.
kaby lake is dual channel only.
You are better served to buy a single 2 x 16gb ram kit.
Do not go cheap on your windows ssd C drive.
Samsung 850 evo will perform better and be more reliable.
Samsung 5 year warranty vs 3 for zotac is telling.
Look to WD for a more reliable 2tb hard drive.
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.
