The 970 runs cool sure, but watercooling will definitely bring about some higher clocks, quieter overall system etc...
So if you were to watercool the GPU I would get a different model that has a supported waterblock. Universal blocks are great and all, and they can be reused from GPU to GPU but the looks of a block designed for the GPU cannot be beat IMO.
If including the GPU I would set budget at $650-$1000.00.
No GPU $400-500.
When I went custom water I dropped about $1500.00 at least. That was in a 900D.
Personally I do not think Bay Reservoirs look good in the 900D and there is so much space for a tube style reservoir that is the way to go.
If you want to flesh out the case I think a 420 rad up top and either a 480, 360, or 240 below. That is more rad space than you probably ever need.
If just doing the CPU's one up top or one below would be fine. The 420 up top would be my choice.
Fans! These can be expensive. Pick a nice quiet fan suited for watercooling.
Pump. I personally prefer redundancy when it comes to pumps, so two pumps in series. One is fine though, up to you and your needs really.
Tubing. If you not using acrylic/PETG do yourself a favor and get tubing without plasticizer.
Fittings. Get whatever you want really. I prefer compression fittings to barbs.
Fluid. I swear by Mayhems stuff, but distilled water w/the proper additives is fine.
Kits. A kit would work fine for you as well. Just get a few more fittings, and another block.
I do a rough plan of where you want everything to go. Tube routing, rad placement, pump and res placement etc...
Do some approx measurements of tubing runs.
Fittings? Are you going to need a special rotary fitting to get a tubing run how you want?
Ok. Let's jump in. Some of these responses may be out of order.
I don't want an acrylic res because as an aquarium keeper I know that it's not decent material.
Does using glass have an effect on what tubing to use?
I can't use cheap tubing. This is a once in six years dream build for me. I can't afford to make disposable systems every 1 to 2 years. This machine will be a workhorse and it will always be on. Component failure isn't an option, so redundancy is key.
This brings me to your comment about pumps. You said two pumps in series. As an experienced aquarium keeper for many years, I know that the are issues with pumps in series due to impeller technologies. Have you ever seen pumps in parallel that are then looking like this? ...
--<=>-- (tubing forks, two pumps side by side, tubing reconverges and the loop is rejoined)
Leaks = can't afford that at all. I have a rig that's run a corsair AIO 120mm on a single i7 cpu since 2009 and I've never had a single issue with leaks. Now that I'm buying better processors, RAM,and mobo that all costed significantly more, that's no way I can leak on that. My fittings have to be flawless and my tubing has to not deteriorate or fail against the test of time. And the fittings can not compromise on quality and risk leakage. This loop has to be watertight like a nuclear submarine.
Since I've spent so much on the system, and still might but yet another PSU just to support all the hard drives and custom loop, there's no sense in getting sub par cooling components. I very literally cannot afford a low quality system for cooling ;-)
Sure, I'm not purposely trying to spend as much as I can. I'm trying to be cost effective and get the best deals on truly good parts.
Given all this, and that I really have no interest in WCing the GPU, what tubing, fittings, and fans do you recommend? Also, is it going to ruin tubing to leak test with UV dye? Also, is the parallel pumps vs serial pumps an issue of concern? What are the glass tube reservoirs that would be best for this 900D in terms of size and brand?
As for the fan areas of the case where I don't fill with rads, do I need different fans than I need for the rads? I think yes, but don't know which.
So many questions and I feel like I've barely scratched the surface.
