The heatsink is 23mm thick so with thermal pads and all that I would guess a total of 25mm from the back of your GPU. An easy way to test if it will fit is if you have a spare fan and just put that between the back of the GPU and the radiator to see if the gap is enough to fit the heatsink. If it is then that's good, but if not then I would strongly sugest that you go for the HG-10 (or any other, fitting mechanism if you are willing to part with the sound card which I personally wouldn't).
I did some preliminary measurements and there is just enough space between the GPU and the CPU's rad though I'm going to get more precise measurements later when I start. If worse comes to worse, the HG10 - based on its appearance, will fit comfortably between the two PCI-E cards unless for some reason it is larger than my CPU's cooling plate (I have no idea what those are actually called). Even the fan should fit from the HG10 just going off a spare 120mm regular fan I have placed on top of the current GPU. So if the Arctic Hybrid II for some reason doesn't work, the HG10 should.

thick 120mm fan. I think having some extra speed would be a good idea.
I have not looked into slim fans that much since I removed my second 3.5 in drive from my media center(needed the slim fan for that).
Check that backside heatsink dimensions for sure. also be sure your ram will clear the rad+fan combo.
I will take a look and see what I can find and get more precise measurements once the new 980Ti arrives. However, from the specifications and what I measured based on the currently installed components, they will fit. It might be a tight squeeze for looping the pipes but I won't complain as the FT03 is a small case anyways so having two separate AIO liquid cooling systems was likely not in the design plan.
The extra speed probably won't hurt as you said. Right now, the fans operate at 700RPM (System Intake) ->800 RPM (Internal Fan) -> 1200-1400RPM (Liquid Cooler outtake). Speeds vary + or - 100RPM usually except in Winter where they run + o - 200 or so RPM.
