that's what I did when I put my 2 EVGA 720 TI on water block.
 

ok i ordered this :
2x EK GeForce 780 GTX Ti VGA Liquid Cooling Block - Acetal (EK-FC780 GTX Ti
1x EK Waterblocks EK-DDC 3.25 (12V DC pump)   1x EK-MultiOption RES X3 250 - Liquid Cooling Reservoir (6 Total Ports)
20ft PrimoChill PrimoFlex Advanced LRT Tubing 3/8"ID 5/8" OD Price per FT Onyx Black
Koolance Quad 120mm, 4x120mm, 480mm 30-FPI Copper Radiator
2x EKWB EK-PSC Adapter 90° [G1/4 Thread] - Black Fitting
6x EK-CSQ Fitting 10mm ID x 16mm OD G1/4 - Black
2x Koolance Nozzle Coupling Adapter Chrome G1/4 Male-Female
tell me if i missed somthing

CPU Block and another Radiator ( 1 up and 1 down)...also, try and stick low FPI Rads or the EX Aeries XSPC Rads..as these perfrom better with low speed fans ;)
Have fun!!!

Your cooling CPU and SLi Titans correct? All housed in a 900D ? If you have a Quad 480mm up top why not go with a triple 360mm below...total 120.7....I had this set up prior to adding the additional 240mm....worked great !!

Yeah you'll be fine...just know how much room there is in the 900D...I wanted to keep filling mine ;)

So your going from your pump to the bottom intake of your GPU's...then from top of GPU's back to bottom Rad? .....naw...keep your flow going in direction and try not to cross tubing (aesthetics), as far as component order really does not matter EXCEPT pump should draw directly from Rez ...
 
I've got:
480mm up top (thick Rad push / pull fans  XSPC RX 480 version 3) - set up as Intake
360mm and 240mm mounted below (both XSPC EX Series single Rads push - set up as Intakes)
3 Front Fans Silverstone Penetrators also intakes
 
* Only 1 Exhaust Fan 140mm Rear / top
 
Loop Order:
XSPC Photon 170 D5 Pump / Rez combo > CPU>Top Rad>GPU>Bottom 360 Rad>Bottom 240Rad > Back to Rez / Pump
 
Ensure you have the correct SLi Terminal Block for your model Water Blocks....newest Blocks require Terminal Parallel (or Series) Bridge....
 
Here you can see my loop order (the tube coming off the top of the Rez is just for filling and bleeding, it has now been removed)

 
Here's pics showing a drain valve coming off both the Pump / Rez and another off the GPU...best to have it at the lowest point in the loop, I've mounted in these locations for easy access....its a standard valve fitting, just nned to attach a length of hose to each valve, open the top of the Rez and rack the valves....done. There will still be liquid in the bottom Rads, but they can be disconnected and removed easily without spilling any liquid on critical components :)
The Bits Power Valves are not cheap !!

 

 

 
 
 

With the new model EK Blocks you want to make sure to use the "Terminal" Bridge, the old style Bridges require a "Links" adapter also which is for the older style Blocks
 
Here's the newer "Terminal Block" (No additional Links required)

This is an example of the older style Block and required Link (Link came pre-installed on older WB's)

Seems confusing, but provided you have the new Blocks (with no pre-attached Links) then you just require the newer Terminal Block.
You'll have to ensure the Terminal Block you have will work for 2 Cards in the PCI-E Slot Spacing you want.
I use top slot....then space....then next slot
 
Thats why I went with the Triple Terminal Block, As my PCI-E spacing means a space between the Cards, so I also have a "blank" covering the holes where the 3rd Card would be mounted on the Terminal Bridge. (this way if I ever get a 3rd Card I dont need another Terminal Bridge )
 
This is the Blank

See also my previous post for more info.....these are the valves I use for draining...they're simple G1/4" female both ends, although the valves are presently closed, I still put a cap in em for piece of mind ;)
