Hi Folks - I'd like some advice. I have a very good knowledge of general rig building, but having recently been left a small lump sum of money from a dying relative (also a gadget freak) I have purchased a Titan Black Hydro Copper Signature to build/rebuild my rig around. Let's say for the record that I have assessed pro's and con's and it is the perfect card for me. What I really need advice on is building/buying the best possible custom loop for cooling this card. It will be matched to an i7-4770k (which will be over clocked to 4.6 [tested] ) and an Asus Maximus VI Extreme mobo..

Hi...
Right.... It's been about 2 years since I last touched my rig.. I built 5 before so I'm not entirely a noob, but also please be gentle if I am a bit out of the loop. 
I have just been offered an exceptional deal on a Corsair 900D (£150 from a friend who bought it 6 months ago and never used it - I snapped his arm off after a brief look online) so it looks like I have space for more fans than the Titan Supercomputer. From what I can see on it I have space for 3 sizeable radiators. I apologize for any typos or lack of links as I'm using my phone at present (bloody work).
I had originally thought about going the Corsair H110i cooler route, but if I have a bit of money to play with it seems the best possible thing I can do is go for a totally custom loop. I'm tech savvy, but I haven't played much in the liquid cooling arena - so I'm looking for the best possible advice. Unfortunately when you don't have masses of experience in a field of interest, it's a minefield trying to find the best possible solution yourself.
Thanks for quick response by the way.

Also, the 900D is a great Case for Watercooling

The best way I found it explained was, 120mm radiator per component to be cooled, plus 120mm extra overall.  So, you are going for one graphics card and one CPU, that would 360mm radiator space total.  Now.  To make it look better and be expandable over time, you would want to go ahead and get a slightly larger setup going, or go for pure aesthetics and keep everything as streamline as possible.  
 
Which is your priority?  You could easily go for a Bay Res and pump combo, and run everything as straight as possible with a large radiator at the top of the case.  It will be easy, clean and look good. 
 
Bay Res - GPU - CPU- Radiator - Bay Res would be an easy line to go with and wouldn't require too much tubing overall. 
 
If you go Tube Res/Pump combo, you can shorten the over all tubing, mess, and lines.  Run from the pump - GPU-CPU-Radiator-Top of res. (if you get a multiport res top)

Do you want me to blow your budget with loop advice or just enough to get the job done?

My God... Thanks guys...First and foremost I realise now that I was, in fact, being a total noob with my questions. I wasn't specific enough for what I really want either. I really appreciate all of the comments and it's already getting things percolating in my brain:-
 
Mdzcpa - I am likely to explore into the territory you are already in. I am willing to go £500-£1000 on cooling at this stage. I have seen that I can easily blow that budget, but if I can bring in a tidy cool/relatively quiet tower within that I'll be happy. 
 
Maybe another basic error here - but I'm not interesting in LED's or lighting it up. So although I am not looking to mess up any airflow, it could look like a Gorgon on a bad hair day and I wouldn't care as long as it gives rock solid cooling.
 
Bcavnaugh - thanks for those guides. No amount of trawling around seems to bring up the same info I can get from aficionado's. 
 
Ideally I would like something that doesn't sound like a Harrier Jump-Jet taking off but gives me enough in the way of overhead that once I have finished; in a few years time when my old Titan isn't pushing those pixels like it used to, I can slip in another 1 or 2 in SLI and still have a decent machine

That looks damn nice... without being rude, what kind of investment are you looking at for that cooling?
 
To give a rough idea of where I am going with my plans... I currently do a mundane job 8-4 and utilize my current rig for a bit of escapism. I am also training to render architectural drawings and the software they use is CUDA intensive. I have the budget for an ASUS ROG G-Sync monitor set aside for when it is released and will pick up 2 (lesser - cheaper) monitors at some point so I can use a decent surround setup... But when I do, I will also want to escape more and for me that equates to beautifully rendered total immersion wholesale destruction.  
 
As always, all help is utterly appreciated
