I think you'll either need a three fan adapters in there, or to build a custom shroud stepping your 140.3 rad down to accommodate 120mm fans. That or go for a 120.3 radiator, or 140mm fans. Is there any reason why you've gone for a dual reservoir with a single loop? future proofing? You'll also need some tubing in there too.
I will put some adapters in there at some point as I can't find any 140mm fan better that the AP-15 I will be cooling the GPU but the one I had on the list is not sold anymore so I need to find one to cover my 560 ti. I know I need tubing but that can be anything as its all the same (other than size)
