You should have room for it on the right hand port of the front radiator, if you mount the top rad in the furthers position from the motherboard.
Its all straightforward really, just time consuming.
I'd run a benchmark on your GPU to warm it up before fitting the block, it will help separating the standard heating.
The top left port of the front rad requires a few fittings to clear the top rad and fans, if you do follow the same route as me, let me know and I'll take some pics of the fittings used.
Where are you mounting your rad?
Have you got somewhere for a drain?
