How much would this CPU custom loop cost?

If I were to cool my i7 6700k with a custom loop using EK parts, a 360 rad, and hard tubing, about how much would everything cost?

Do you actually need water cooling or just for fun ? Because watercooling tend to be very expensive.
Easily over 300€ (300$-400$)
it's not going to make huge performance improvements 😛
