So I am looking to move away from my AIO cooler and build my first custom loop, but I am not sure wether or not I can get away with the size or rad I would like to use. My system is housed in the corsair crystal 570x and those of you that are familiar with it will know that it is a little short of space in the roof, you can get a rad and what not up there but it reall obscures the view of the top of your motherboard aswell as almost touching the memory but there is room for a nice 360mm rad in the front of the case. My question is would a 360mm rad be enough to cool my oc 7700k, my freshly ordered strix 1080 TI oc which I won't overclock further than it comes, and the EK crosschill mossfett cooler on my Maximus IX formula? Or am I going to have to leave the crosschill out and just have the 7700k and the 1080 TI in the loop? Hope you can help guys as I am not entirely sure about this despite trying to read up on it.
Is a 360 enough?

If the loop is designed well (no flow issues or starved fans, etc.) then there will be absolutely no issues with temperatures. Your CPU might run a tad hotter than if you had a dedicated 280mm AIO, but the benefits to the GPU will be totally worth it. I agree with Lynx, 800 RPM fans would do nicely.

I've got a single PE360 rad cooling my 6850K and 1080 Ti and am happy with the temps. My case isn't the best airflow wise and I still get temps below 50C on both CPU and GPU unless the weather is really hot and they may rise up to 55C.
If I take the top of my case (as it's solid with no vent holes) the temps drop to under 45C for each component.

This is a little ooff-topic (though still relevant) but there is an enormous discussion on OCN regarding your case and ways to optimise temperatures. There is an image I'll try and find that shows lifting the roof off ever-so-slightly massively improves temperatures, and if you stuff up the empty spaces in the radiator/fan bracket with material then the hot air that is exhausted into the top chamber won't fall back down into the case and be recycled by the fans thus inefficiently cooling the radiator.

Yup, way ahead of you haha!
I've got the case resting on top so there's a 4mm gap and it makes around a 5C difference. There aren't any spaces in the rad tray as I'm using a 360 up there.
I'd like to get the front and top panels cut but depends how much it costs!
Thanks for the info guys much appreciated 
I think I will go ahead as you guys suggest although I had started to consider having a 360 in the front but also running in an Alphacool Eiswand from the outside so that I could watercool everything and still have a really good overclock on my 7700k, pricey I know but maybe better to have more rad then I need then too little.

Does not seem too bad with the Eiswand, would literally just have to make two holes in the bottom of the case for inward and outward. Can then go in to the case and first go through the GPU, in to the CPU, then to the mossfett cooler before going in and out of the interior 360 rad and back out of the bottom of the case back to the Eiswand, it has 2 pumps inside the unit so it should have no problem pushing the coolant around the loop aswell as a 360 rad with 6 120 fans on it.
