If noise is a bother to you, I suggest a good air cooler instead.
It will also help with your airflow.
I like the looks of your case, and I think you can make it work without a lot of expense.
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? What is your cpu, and how high do you need to overclock it?
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.
It looks like you have the ability too have 3 or 4 120mm intake fans providing sufficient fresh air.
That results in positive pressure cooling.
If you filter the intake fans, your innards will stay dust free.
No need for exhaust fans which are optional.
A air cooler with two 140mm fans will extract all the heat from your cpu efficiently and quietly.
Look at noctua or Phanteks. If your ram is low profile, the nh-d15 is as good as it gets. Otherwise, a tower type that clears the ram should be used.
A plus with air coolers is that your motherboard and graphics card will stay cooler too.
