New to overclocking/water cooling, suggestions please!

[BMRX]

So water cooling is something I'm having a growing interest in and will be my next big upgrade to my PC.

Specs:

• 
  Intel i5-4690K 3.5 Ghz
  Asus z97-A
  wintec random cheap RAM 8 Gb's
  Evga Geforce 750 Ti
  Corsair 650W PSU

Now the plan is to purchase the Geforce 970 more specifically one of these:

or
http://www.newegg.ca/Product/Product.aspx?Item=N82E16814133564&cm_re=GeForce%2bGTX%2b970-_-14-133-564-_-Product

(I'm leaning towards the PNY)

When I buy my new GPU I also plan on buying newer RAM as well as all of my watercooling/overclocking parts.

But I have no clue where to start, from what I gather buying a pre-made kit would be more ideal.

I don't even know if I want to overclock her or not. This is a gaming build but I also use it for quite a lot of things at once. But I am very interested in water cooling ever since I saw a water cooled build in a local PC shop... Was it ever quiet!

Anyways, what would you fine experts suggest?
