New Gaming Case

Solution
Considering the level of hardware you have, if you were to put it in a loop you would need a massive case to handle all the radiator space, or look into an external rad-box option if you wanted a smaller case but still have everything under water.

The best possible case would be a MountainMods/Caselabs monstrosity, they are absolute beasts in how much hardware they can handle. Something like a Caselabs M8?

The main advantage of something like a 900D is its impressive water-cooling capability, to not water-cool in that case would be losing a lot of its value. Whether its other aspects make up for that, that's for you to decide.
Another good water-cooling case the Phantom 820 is, when your looking at this high end you will find that water-cooling support is practically a must.

In terms of air cooling support, all will be about the same. Your main issue with temperatures will be because the cards are packed against each other, not really due to a lack of airflow through the case.
