Looking at the 900d case again, even if both h220's fit I don't think the tubes will be long enough if going from bottom of case to top...then I'd have to mess with replacing tubes and it gets messy from there. Need a clean solution.
 
But wait a minute. You have two X5690's and are using two H20 corsairs right? And you're getting...oh wait, you're getting only 4.1 GHz. Hmm, I wonder if I'd get the 4.5 Ghz with two H75's like geok1ng suggested..although he didn't say what clock speed would be expected with that config.

And yet you got real good benchmark scores with the stockfish benchmark...or was that geok1ng?

Buy the Roswell (save money) call frozen cpu and buy a good custom kit, order straight fittings and some 90's so that you can lay out your loop (waterlines with no restrictions) I have given you the case dimensions already. Hook it all up and enjoy!

and don't forget the coolant the cheap way is go to a DIY store an buy distilled water or what ever you like from this list http://www.frozencpu.com/cat/l3/g30/c103/s753/list/p1/Liquid_Cooling-Coolant_Additives-Distilled_Water-Page1.html

the other ex480 whil be dilivert whit 4 fans.
the rx480 whil perform a bit beter,radiator almost dubbel the thiknes of the ex480
rad of the ex480 is 121 x 35.5 x 515mm (WxDxH)
rad of the rx480 is 125 x 58.5 x 534mm (WxDxH)
 
and for 15$ its a nice extra of cooling performance

i asume thad the block thad i linket its the same as in the kit.i do'nt find other RayStorm Intel CPU Waterblock blocks than this 3

if you go for the 1/2id x 3/4od fittings you gone need to order 8 fittings an the ccorect tubing for the fittings.
i have found the demension on http://www.highflow.nl/radiatoren/4-x-120mm-480/xspc-rx480-quad-radiator.html
this ar the items thad you need to order if you go for the xspc kit

Then perhaps I should just stick with the fittings you mentioned originally so that I don't have to buy so many fittings? And why would I need more anyway? I'm still just adding one cpu block that should require only 2 extra fittings.
 
Why do I need the extra bracket? What's it for? That kit already comes with brackets:
 
RayStorm Intel CPU Waterblock
D5 Photon 170 Tube Reservoir
D5 Vario Pump
RX480 V3 Quad Radiator
G1/4″ to 7/16″ Compression Fittings (Black Chrome) x6
XSPC 1650rpm 120mm Fan x4
120mm Fan Grill (Black) x4
Intel and AMD RayStorm Brackets
Socket 1366 and 1150/1155/1156 Backplates
Socket AM2 and AM3 mounting kit
80mm to 120mm Radiator brackets
3mm Twin Blue LED with 4Pin Molex
5mm Blue LED with 4Pin Molex
2 Meters of Clear 7/16″ Hose
24pin ATX Bridge Tool
K2 Thermal Paste
 
So will the Rosewill case fit this large rad? And am I better off using arctic silver 5 thermal paste instead of the K2 or it doesn't matter?
 
What other fittings can I use? The ones you suggested are now Out of Stock!
 
Lastly, manual suggested ec6 coolant so perhaps XSPC EC6 Coolant - 1L UV Green ($15.99) or it doesnt matter?

Dont waste money on coolant. Buy Distilled Water and a kill coil

sorry i missed thad,you don't need to order extra bracket.
about the fittings,if you go for bigger you need to chage all of them 2 per pice (cpu1 , cpu2 , pump whit res and rad) so this makes 8 new bigger fittings.
and fittings ad alot to the cost of a wc kit.
thermal past maks a big diferent in temp whet evry cooling type.
i dont' know how good / bad the K2 works
evry whone have it's owne favorit, i use arctic cooling MX-2
ths is also ar very good past

MX4 is the current leader in thermal paste 

not my system,i found it on http://www.overclock.net/t/1184838/rosewill-blackhawk-ultra-and-evga-sr-2-build-log.
i am not 100% sure if the 480 whil fit whitoud modding the case, but a 420 or 360 whil fit whitoud modding the case

its a trippel rad setup.
2x phobya 140 and a phobya 420
the sr-2 have a ek waterblock on it

i don't think thad ek is stil making this blok.
bitspower have made a block for this bord but its also end of live.
alphacool have a block for the sr-2.
here on the forum is nateman_doo ho maks wc blok,and i thik he is stil fabricate blocks for the sr-2.
http://forums.evga.com/NEW-100-Copper-SR2-full-coverage-waterblock-m943648.aspx
if its your furst time whit wc i don't recomand to put the bord on water
 
but if you don't mind to try it.
this is wat you wil need for the bord

Hmm. First of all, me and skulstation have decided and been talking about the Rosewill case, not 900d. 900d is so overpriced and the Rosehill should allow for whatever the 900d does, unless you know of something we don't.
 
"As you can see, 25x turbo multi is essential for these results, and i am nowhere near 200 BCLK, so investing in high speed memory or extra motherboard cooling will not help someone with a 5680, which can do 26x Turbo."
 
Not sure what this means. If my 5680's can do 26x turbo then 26x or less is possible. Now, what does it take to achieve 26x is the question. I thought I'd need the extra cooling to allow for the higher mutiplier hence stability? If not, then why cool the board? I guess we need to determine how YOU achieved 25x at that block, and try to go with the same equipment...this of course assumes the chips I'll get can be OC'd to 4.80 GHz. Btw, what temps did you get on that last run with SF? Are you 24x7 stable at 4.8 or 4.7?
 
Again, I just want to get as close to your OC as possible so please suggest everything I'd need to accomplish this goal.
 
Btw, I got a chance to test run that used SR2 with 2x5650 I originally mentioned and with the SF benchmark I got to nearly 17,000 kN/s after about 5 mins at that position. For $1300, maybe it'd be much cheaper to go with that, at 3,000 kN/s less than what you got...and he got that at 4.2 GHz I believe. Although it's too late now anyway as I've ordered the 2x5680's already and am going out now to pay for the SR2 from malaysia at Western Union (keeping my fingers crossed).

don't be regrated to go whit the x5680 setup.fingers crossed for a fast delivering 

idd thads it what i mean.sorry for my bad english,its al self education.
tomorow i whil run the benchmark,i need to instal a new daily os.
