Water loop layout & water fittings
Basically the checks I did earlier in the build confirmed I had a usable enough loop, and also taught me a few things about what works and what doesn't with various fittings and positions of things once inside the case. A few things were obvious without the checks, but I felt reassured checking some of these things through anyway. Here's the outcome...
For now at least the first iteration of the build the loop layout will be as follows:-
Single loop: RES - DUAL PUMP - FLOW METER - RX360 - RX360 - CPU BLOCK - GTX 580 - GTX 580 (series configuration) - RES
The case has plenty of scope for adding another 360 radiator on the PSU side (I already have the bracket accessory for that), and I could potentially try this loop with the graphics cards either in series or parallel (I'd just need to buy a parallel bridge, as I have plan to use a series one in the build currently). There's also plenty of room for me to try dual loop in future if needed, but that's a long way off I am using some of Jim's excellent caselabs promo shots modified to show my intended loop design (I hope you don't mind Jim!)
On the motherboard side I tried to go with a real clean loop design to keep nice aesthetics when viewed through the window
On the PSU side there is not going to be much room once the HDD bays and PSU are fitted, so the tubing on that side is very simple. If I do add another rad I will try to keep it that way

As I describe in the posts above, the reason for the slightly odd radiator flow with "swapped" in and out flows on each side is because I didn't want to use a complex set-up in that area of the case since it lies directly over motherboard and graphics cards. The options apart from the one I am going to use were
- Use some extender pieces to go from the through panel (fill port) fitting to the MB side radiator (like on the PSU side) - unfortunately this length is bigger than it is on the PSU side as the case is asymmetric in that regard. I couldn't find any fitting exactly the right size (like I did on the PSU side). Building a chain of extenders seemed to be introducing unneeded points of potential failure/leaks and so I avoided that.
- Use some 90 degree compressions there (which I tried) the problem here was the piece of tubing needed was very small and difficult to work with since the two compressions were so close and right in the corner, again I thought this seemed more likely to cause potential problems than solve them.
- I could of used the pre-existing grommets and loop the tube outside of the case, but I did not really want to do that. I'd like to keep everything inside
As it is now the current configuration actually allows for a slightly less long/loopy looking piece of tube to go between the radiator and the CPU block as the radiator outlet is physically a little closer to the CPU. As you can see from the previous posts that shows this area I will use white Primoflex tubing in the build.
To achieve all this I had previously cut a the mid panel of the M8 to allow a through port configuration using a bitspower fill port...
Measure and tape!
End result - Unfortunately I don't have any shots showing the connection made up on the PSU side using a 90 deg bitspower fitting an extender and an anti-twists.
As regards fittings I learnt a few things from the experimentation
Firstly I decided also that I didn't like the green O-rings and so got some bitspower red o-rings to fit in with the overall black/red/white case colour scheme. It may be over the top as the O-rings are not exactly visible when used, but it would pain me knowing they weren't just so (yeah I know its a bit OCD!)
Next I changed the drain port T- Junction assembly, in the posts above you can see the drain pipe coming towards the camera - I had this terminated with a koolance QDC, but with 3/4" tube and a small gap between the AX1200 PSU and HDD cages there was no real way of positioning a decent length of drain pipe there. In the end I found I could create a T-junction and place a valve+stopper there.
I think this will work better and is more pleasing to the eye compared to what I tested. It will just rest on the base of the case in between the PSU and HDD cage, it should end up being the lowest point in the loop by default that way. I have a matte black bitspower valve on its way to me to swap out the koolance one.
Finally I messed around with a lot of ways of getting the flow out of the pump, through the hole in the M8 mid panel, and then down between the side of the of the mid panel and HDD cage - Its a tight fight and to do to this I will use some double rotaries and a straight compression. The actual configuration may need to change now I have decided to use a dual pump setup.Edited by alstorm - 4/10/15 at 3:51am
