Any suggestions?
It's a bit of a monster case: "Cosmos 2" from cooler master. Looking to get 4 1080 Ti's (no SLI for compute only) on the top 4 pcie. 64GB of GSkill Tridentz 3200. Probably put in another 64. 1 tb Samsung M.2 NVME that my x99 classified joyfully figured out!
Yes, my cable management is a mess
 

 
Pending purchases: 2 more 1080 Ti's and 1600W T2... and a bunch of pumps, tubing, fittings, radiators... this would have been fun in my 20's... now it seems like this might just be work :-)
 
Flexible vs Rigid tubing?
The cheap 1030 beneath the top Ti will be relocated to bottom for basic graphics output, simple air-cooled is plenty (and $85 card)
EKWB 2 pumps in series with 100 reservoir on top
run the loop through both the GPU's and CPU? or Leave CPU as AOI?
Space management, I have tons if I remove the bottom plate, the lower SSD area is empty
for 4 ssds and a old spinner that I will need to locate somewhere.
The 1080 Ti's will of course be EKWB complete cover blocks
 
Yes, this will be a project.
Any suggestions?

 
just get some zip ties in that case, and it will look better.       =)

I get some extra-credit for doing a "GamersNexus" mod to the 1080 CLC to fit the 1080 Ti's ;-) Would look a *lot* better if just Ti's were just factory air-cooled without the clc tubes - but MAN, what a diff liquid cooling makes, even just the evga CLCs. Never got above 50C on Timespy with no artifacts no matter how many times I ran it without breaks.
 
I did not realize how hot these GPU's got until I began pushing models onto them (yes I'm an idiot). Made me a huge believer in liquid cooling.

Cool GTX
Step 1 decide how much radiator you Need
 
Step 2 research how much radiator will fit in your case, unless you mount them externally
 
Step 3 where to mount pump & reservoir
 
Step 4 how your going to plumb the GPUs together
 
Step 5 Which fans & fan hubs your going to use
 
Step 6 Type and number of fittings and hose size
 
-Size matters -- thicker radiators are better
140mm radiators offer much more area if your case can fit them
 
Flex line is easy
Hard line is more for aesthetics -- they have a bit of a learning curve
 
 Ready to try water cooling. Where to start? Library of links-basics to expert
 
 
 
 

Yeah, that was a bit of a question, a 280 would actually fit in there better with everything else than a 360. Not going to do some formal heat transfer analysis but it seems like 280 should be enough surface area. Maybe keep the aio for the CPU and custom loop just the GPUs, have the GPU radiator blow out the front and clear the bottom for the pump + reservoir + tubing.
 
Flexible is definitely the preferred choice.

1. EVGA Sleeve Cables for PSU
2. EVGA Power Link for GPUs 
With these two options you will not see cables at all than other things.

EVGA Sleeved cables are very nice. Word of experience.

Vlada011
 Your PSU look much cooler with Sleeve cables.
Completely different situation.
It's doesn't matter did I see them or not I like to know that they are inside, on some parts are always visible.
Maybe EVGA should add one more color, some version of grey, Titanium Grey or Platinum Grey.
Why not, they fit with full black RIG.

True that.
I have been wanting for my next build some kind of Grey / Lead / Titanium type.

This wasn't very nice....

Yep, I had no idea that one was coming...

The BEAST has arrived. Words (and pictures) do not do justice to how massive this card is. It is every bit as weighty as it looks - and then some...

EVGA 1600 T2... on it’s way!

Going to go with new caselabs case for new build out.

Either:

Mercury S 5 (flat layout)
http://www.caselabs-store...-s5-case-customizable/

Or

Merlin SM 8 (vertical / standard layout)

http://www.caselabs-store...sm8-case-customizable/

The cooler master is a bit of an old moddl and a nightmare to mod. It go bye bye

 
MERCURY S8S LIMITED EDITION GUNMETAL!
He is smaller, cooler and accept all form factors as S8.
 
I'm so sad because I can't afford that case, he would cost me arround 650 euro in  Europe.
Because of that I need to wait Bullet BH8 to arrive, but S8S is my BIG WISH.
I always thought that S8 is to big and S5 size could be compatible with E-ATX.
Than they build S8S.

I see you order EKWB ACF fittings.
Only doubt I have about fittings for me. I need to order these days radiator CE280 and 10 fittings but I want without any mark Nickler/Chrome/Silver depend how call them.
EKWB ACF have sign, Bitspower bottom part is somehow wider than top on 13/10mm 3/8 1/2. I would payed for Bitspower if need but like I sad bottom part is somehow wider on pictures...
Than I saw Alphacool new series from 2016 could be find 6x for 25-26$. Alphacool Eiszapfen is name. But I didn't found experience from users.
Price and look are great, adapter could be used EKWB because no logo.
On some pictures is even bigger difference, only Bitspower 13/10 is like that...
 
   
You will use big waterloop and than you need Dual D5 Revo. I have option to buy very cheap Dual D5 Revo with top as you order, for half price and used very short time.
But that completely change whole concept of build I plan and I don't need dual pump or big reservoir. 80-100 is for me. I need to plan for my case now and for BH8.
You computer will be fantastic. It's best when you have enough to build immediately everything. 
 
 

I think your choice of cases is excellent.

I think your choice of cases is excellent.

Thank you!

I quickly began to realize that modding “cosmos 2” would make me want to jump off of a tall building...

rjohnson11
Looking forward to the updates to come.

I'm in about ~6K right now with the new PSU (big beautiful monster). I might tear down the Cosmos after all. The water blocks and rest of the plumbing are gonna set me back another ~1,500 - Will have to wait for bonus in April to continue on with what my wife insists is an expensive hobby...
 
Some people... they just don't "get it" :-)

This is a pretty sweet project, not sure if you already choose the parts but from what I understand you want to watercool 4x 1080Ti's and other components, I would do dual D5's and use EK QDC's since you are using EK ZMT.  Not sure what case you plan on using but 4x 1080tis will dump a crazy amount of heat, you will probably need a very large case for this so you can get as much surface area for heat dissipation for the rads. Trust me using QDC's in your build, it will help out a lot when you change parts or need to replace coolant.  For coolant I would highly recommend Aquacomputer DP Ultra Clear.  For fans there are too many to choose from, but I would recommend EK Vardars, or Gentle typhoons, but entirely up too you.  As for controlling those fans I would recommend using an Aquacomputer Aquaero 6.  As for radiators, as many as you can fit practically.  I would recommend Hardware labs or EK XE/PE rads.  For fittings I would just get the EK ACF ones, they work great and are not super expensive  Best of luck with your build.   
 
One last thing, get a Dr. Drop Pressure tester before you fill your loop and test components, could save you.

@Krzysztof47, the OP has been banned. Not sure for what, but there looks to be little point in suggesting anything further.

Did not know that, thanks for the heads up.
