Help requiered for £3000 rig with custom watercooling

Hi guys I hope you had a great Christmas :)
Unfortunately for there is not good looking EVGA 970s waterblocks yet.
For watercooling system I am thinking about :
Radiators EK-CoolStream PE 360 + EK-CoolStream PE 120 (front and back)
CPU http://www.ekwb.com/shop/blocks/cpu-blocks/supremacy-evo/ek-supremacy-evo-nickel.html
Reservoir http://www.overclockers.co.uk/showproduct.php?prodid=WC-518-BP + http://www.overclockers.co.uk/showproduct.php?prodid=WC-319-BP +http://www.overclockers.co.uk/showproduct.php?prodid=WC-328-BP ( I like how does that combo look like)
I am still not sure about which acrylic tubing and fitting size is the best way to go.
Another thing which I have in mind is to build a normal rig and wait for the EVGA waterblocks to come or go for MSI with http://www.overclockers.co.uk/showproduct.php?prodid=WC-736-EK + EK-FC970 GTX WF3 Backplate - Black Anodised Aluminium .
It takes quiet long time for me to do all the research about parts and what I need because I was working a lot in the past few weeks.

The strange thing I've found on EKWB-playground the 1st EVGA GTX 970 gpu
step1_complist

EK-FC970 GTX - Nickel [3831109869413] shows as Acatel. Is it a mistacke? can someone double check it?
 
I don't know if this has been mentioned yet but....

Have you considered changing that Core i7 5930K to a 5820K?

A 5820K can easily be overclocked to a 5930K speeds though it has the disadvantage of 28 PCIe lanes instead of 40.

You have only 2 Graphics cards (GC) running so when using a 5930K, 16 lanes will be dedicated to each GC putting your total usage to 32 lanes out of 40.

If you were to run a core i7 5820, one GC will use 16 pci lanes, and the other will be reduced to 8 lanes putting your total usage to 24 out of 28. Theoretically, this does bottleneck one of your GCs by reducing PCI lanes but I have not seen any convincing evidence that any GC out there including the latest geforce 900 series can fully saturate the bandwidth of 8 pci lanes.

This might save you 200 pounds ish? Sorry I have no idea of the prices of computer parts in the UK. In Japan where I am from they are ridiculously expensive.

==========================================

Regarding water cooling, have you ever heard of XSPC? They do have reservoirs made of glass and aluminum which presumably would be sturdier than acrylic. I am thinking about buying XSPC parts for my PC later.

Thanks for your reply Xen, but I've already gone for 5930k because I might adding more GPUs If i'll decide to switch to 4k res. I am not sure but wasn't 8 pci lanes not enough since 7xx series ?
 
I drew a simple diagram about the loop, since it is a reverse motherboard it is a bit hard to start from GPU. http://imgur.com/VWIrJsf
The only thing which is a bit considering for me is that there is 3 intake fans at the front ant only 1 outtake at the back which would make uneven pressure inside the case.

Thank you stulid, I just want to be sure :)
On EKWB website they put the wrong image on the nickel one, but when you go to their or Overclockers shop the code matches Nickel GTX FC970 one :)
Any suggestions about my loop ? Maybe I should drill the bot and put 240 rad and make it blow to the bottom ? What part do I need to put between D5 Mod top and a reservoir to join them together ?
