I have a corsair h100i v2, I am currently only developing with that atm. I am currently using the protocol from https://github.com/audiohacked/OpenCorsairLink which supports pretty much all corsair products. I dont have the money myself to buy all the products available but https://github.com/jonasmalacofilho/liquidctl has other devices available. They are both GPL licensed so that should be no problem. I have no idea who would test other products/brands, but since a lot share the same controller it might not be that big of a deal.
