Question Question about top radiator support for Corsair 460x

[Baconbits99]

So I want to get an AIO for my CPU (currently an I7 7700k) and I'm not sure if the radiator will fit on the top. I don't think it will fit in the front either due to my GPU.(see pics at the end of the post to see what I mean) Some places say you can fit one, others say you can't. What I am worried about is my ram getting in the way. Alternatively,the new Noctua black edition of the NH-d15 looks nice but I believe having both fans on would cover the ram.
So overall I want to know if a top radiator will fit in the 460x and if it needs to be a slim one which would be the best?
