question of fitting in a CM690 II advanced

[innui]

Hi first time poster here so be gentle!

I'm looking at a CM690 II advanced, an asus sabretooth p67 board and using a corsair H100 and curious if the radiator and fan will clear this armoured motherboard using the top fan mounts.
I was under the impression that (after seeing one actually fitted) it was a tight fit and some boards/cpu locations might scupper fitting one.

Otherwise would a H80 do a good job at keeping the i5-2500K cool enough when it's overclocked to 4k or so?
Thanks in advance for any tips, guidance or outright help

Doesnt the H100 have the standard 15mm gaps so I can not see it being a problem fitting it to that case.

I have no idea. It seems quite hard to find out how well it fits in what case with what motherboard though

Thanks for the responses everyone. I've decided to go for the H80.
It's a shame that there isn't more info on how easy it can be to fit certain things together as it would really help with making a decision!
