Not sure if you'll ever find a case that is 100% perfect. I'm not a big fan of the Cosmos S, I have a Cosmos 1000 and like the refined lines. I'm sure the S is better in terms of cooling but like I said nothing is perfect. That said with the S probably being better than the 1000 in terms of cooling a triple rad is pretty easy as IIRC it will just bolt right in. I have a dual loop in my 1000 using two chevette HC's which are 6"x6"x2" plus shrouds and plenums and still have room to mount at least a triple and a single rad so there's definitely room to grow. The 932 is, well, a matter of personal preference. It has lots of big gaping holes and big fans so if it fits what you have in mind then it could be the best option for you but not very sleek IMO.
