Where do you find a reference graphics card?

Well either way I don't really care what it is I guess whatever one is cheaper, corsair is releasing a gpu bracket for water cooling gpus, however it only supports NVIDIA’s GeForce Titan Black, Titan, GTX 780 Ti, GTX 780, GTX 770 and amd reference 290 or 290x, which I'm actually kinda mad about but we can work with it. Also does the NZXT G10 bracket support asus 280 graphics cards?
