Hello,
First of all, I'd like to warn you that my questions might sound stupid but I need some answers and I'm ready to assume the consequences.
I'm wondering about buying GTX 780 Ti Dual Classified w/ EVGA Hydro Copper Cooler.
I don't know a lot about watercooling so what can you suggest for this card ?
I couldn't find any information on google or this forum. All watercooling kits I found are rather for CPU and for the ones for GPU require replacement of air fans by watercooling heatsink.
Are there any watercooling kits for EVGA Hydro Copper card or I need a custom setup ? On the official requirements of this card, there is no information about a watercooling system at all…
I have this Zalman ZM-T2 PLUS computer case: (bought recently because I need a case of this size and not bigger)

I’m looking forward to your advice.
Thank you.

I like to look JayzTwoCent's clips too.
 

First question is how much do you want to spend?
Second question is do you plan on adding anything to the loop in the future?
After looking at your Zalman case I'd suggest going with a outside the case rad like the following,

You can check out my mod rig and see one.
 
 
 

Thank you for your replies.
Actually, on my Zalman case there are 3 holes at the back, I guess they are for watercooling tubes, and on the side I have enough space to fix two 120mm fans or maybe a 2x120mm watercooling radiator.
 
The point of buying a small case was to be able to put it in my luggage while traveling for holidays to see my parents and there were no point of buying a laptop just for a few days per year.
So, now I'm wondering will it be safe to travel will a watercooled case in a luggage. :)
I just hate noise of modern graphics cards. Wondering about buying EVGA GTX 780 Ti Superclocked w/ ACX Cooler or Hydro Copper edition.

I would advise on joining a site like overclockers and the likes to learn the basics of water cooling.  You'll want to research to get a better understanding of the basics.  It's really important to do it right the first time than learning your lesson.

I used to hate the noise that my system generated, all the fans and blowers from GPUs etc.  So I went the water cooling route and loved it.  It's more work setting up, but I also don't find myself buying new computer parts every two months.  I started with XSPC as they have a reservoir and pump combined. http://www.xs-pc.com/water-pumps/acrylic-dual-bayrespump-combo-with-one-ddc  They also sell kits with rads and CPU blocks.  You don't need to use their block or even do the CPU.  So basically you'd need some tubing, fluid, and additive for the fluid (bacteria and corrosion).  All that being said, I've be very leary of putting it in my suitcase traveling with it.  The systems are sealed, but not necessarily that tightly.
 
There are some forums here which help with water cooling and the guys there are really good. 

Yeah but its pointless only doing the GPU and not the CPU.  You'd want to do both but understand the basics and maintenance involved and the amount of heat surface needed to cool and keep your operation at low temps while keeping it silent on full load.
 
XSPC has many great starter kits to start with.

Thank you for all your advice.
I traveled a lot with my computer case in a luggage, never get anything broken or stolen. Maybe I'm lucky :)
I think, I'll wait a little before getting a real watercooling system with a real not portable computer.
