Is it reference design or cu2?

 
Moving to General Hardware.

Just an FYI , I have seen many reply by saying that the RAM cooling is not really needed. Are you starting from scratch on w/c or do you have any parts yet?
Oh, and welcome to the forums!!

True about the RAM cooling but I figure if I am going to do it I may as well go all out and cool everything. Frozen CPU even has water blocks for HDDs. I don't have any parts yet but I am looking to put some together. I could really use some pointers on a really reputable setup.

Here's a thread with some sound advice from one of our great water cooling guys. http://forums.evga.com/tm.aspx?m=2120637
 
Basically you want [at least] 120mm rad for each component, for your 2 GPU's I would use a 360 rad if possible. Try to avoid the colored coolants, instead use colored tubing if that's your thing. And the most used coolant is distilled water with either a silver kill coil or a biocide to prevent mold and nasties. http://www.frozencpu.com/products/11441/ex-tub-705/IandH_Silver_KillCoils_-_Antimicrobial_999_Fine_Silver_Tubing_Reservoir_Strip.html?tl=g30c103s186

Loop order I have read really doesn't matter, because it will eventually equalize temps. When you build your loop take into account a way to drain the system, this can be done with a simple T fitting and plug. A popular choice to use : http://koolance.com/drain-valve-for-id-13mm-1-2in
 
DO not mix Aluminum with copper, ect. It can cause corrosion and other issues.
 
 
There are lots of choices on reservoir's you can go with an all in one where the pump is in the res. , or you can go separate. On your case I might choose an all in one, BUT it could be done many different ways. Here's an example of a pump/res combo : http://www.frozencpu.com/products/16259/ex-pmp-197/XSPC_Dual_525_Bay_Reservoir_Pump_Combo_-_D5_Vario_Included.html?tl=g30c97s152
Love that case BTW.  
 
 
As far as fittings it is personal choice. You can go with the simplest barbs where the hose just pushes on, or compression fittings the fitting is the barb and clamp in one. The barb fittings use a clamp, on the compression the tightening of the nut is the clamp and gives the cleanest look IMO. Then again it's personal choice. Make sure w/e size tubing you go with to buy matching fittings. A popular choice is 1/2x3/4
 
When you have everything assembled don't be tempted to power on PC. Matter of fact don't plug in motherboard until after leak test. Leak test is performed by either using a premade jumper plug, or jumping the green pin [on 24 pin plug] to any black pin to power up PSU. http://www.frozencpu.com/products/5141/psu-218/FrozenCPU_24-pin_Power_Supply_Jump_Start_Connector.html
 
 
And one thing I recommend are quick disconnect fittings. This enables you to take out each component without having a huge mess. It is a convenience when you have a failure which may or may not happen. It does of course add to the cost.

All the choices I have listed are just options to show what is available, you are free to choose w/e direction .
 
You might take a look in the marketplace for some of your components. I have seen fittings,
,reservoir , pumps and rads for sale. Could help save some $$. Unfortunately you need 50 post's to be able to see/use it. Hope that helps. Enjoy your build!! 
 

Gary @ SideWinderComputers was a pleasure to deal with when I was building my first water cooled setup, hes quick to answer emails and can help if you have any questions/need advice.
If you're located in the USA you may have a MicroCenter near you, they have a lot of parts in stock with some pretty decent prices. 

So if I am ordering:
7/16" ID / 5/8" OD XSPC HighFlex tube, what size compression fitting do I need? I guess... is there a tubing to fitting ratio sizing chart or something?
 
Can anyone recommend a waterblock for the Asus GeForce GTX 780 GPU?
 
Thank you for the help. :)

You should also post a build log in the mod rigs section here. We always like to see cool projects and hardware. It doesn't have to be EVGA for that matter. Good luck on your build.
 
Some people buy the 7/16 tube to fit on a 1/2 barb for a really tight fit. If your going with compressions you will need the appropriate size. They do offer the cleanest look in a build.

 EKWB seems to make pretty good Waterblocks all around.  It may not be the look you are going for though. XSPC makes some nice looking black, but never seen the reviews for one.  
 
About the 7/16x5/8 tube, you answered your own question.. get 7/16x5/8 compression fittings...  ....  ...  The compression fitting it advertised as what size hose it fits... so, if you were getting 1/2x3/4 hose, you would get the same compression fitting.  it's a game of match the numbers.
