Would it make any more sense to run two 240mm radiators, one at the bottom and one at the top?
Also, I plan to use hardware labs radiators, are those very thick?
The case is good to look at the outside but the space inside is pure waste if you're going on full liquid cooling. For such a high quality case, CM failed to realized that those buying this type of case will use it mainly in a full liquid cooling set up (with everything packed in the inside).
For such a huge case, it's really hard to get its maximum cooling potential due to its design limitations. Yes, you can definitely put two 240 radiators but you need to do some modding on the one at the bottom as the bottom is made to house the hard drive cage. At the price of about $350 you suppose to get everything without the need of significant modding.
I'm not a fan of placing radiators facing down at it creates significant heat on the surface.
I rather get HAF X
than this case if I really need a case that I can put everything inside without worrying about space. Or my personal favorite which I'm planning to buy next month, the Mountain Mods Dream Machin
e (costs the same as the Cosmos II).
By the way, Hardware Labs
radiator is a good choice. I used their second generation radiators & so far been so satisfied with the performance. Yes, they have thin & thick radiators.
