Triple rads aren't 360mm long. The one that soloz has is 397mm long.
A rad that big would fit in the front of the armour. You'd have about 1cm gap either side of the rad, and it would be VERY close length/height-wise.
It would also mean you can only have 2 drives. (Like when you use 3 iCages)
IDK what you could use to hold the rad though. Although im not getting a WC setup any time soon, it is something i've been thinking alot about recently.
I was thinking of turning the iCages around so that the fan mounts are towards the inside of the case. But i can tell you that this will NOT word, as the screw holes on the iCages wouldnt match up with the rad, plus it would mean the rad would be quite far inside the case, and would be in the way.
I'll be keeping an eye on this thread, as i'd like to see how you put it in the Armour. (if you choose it instead of the CM stacker).
Remember, because the armours PSU is mounted vertically you can put a res/pump what ever in the rear HDD cage if you need to. Although if you had the rad in the front you'd need this cage for.... a HDD! (make sure your SATA cable is long enough to reach it!)
And i have to say about the armour: You can't go wrong with the Armour man. It's huge and you have so much room to work with.
Why go with the CM Stacker and put a triple rad in the top like everyone else with a triple rad? Do something new and unique! (ie, armour.)
You could try something with the rad like what Cyber did in his 'water clocker'. You can see it in Cyber D's build log.

FYI: Need any specific measurements on the inside of the armour just give me a shout, and ill grab my tape measure and pop her open
