Choosing a case for a noise optimized WC loop

[doublethink]

I'm planning to build my first water cooling loop optimized for quiet operation and good aesthetics.
The loop will be: i5 cpu , 1x high end GPU with possible future sli Rads: 1x 360 1x 240 I'm looking for a case that will compliment a "silent" loop.

So far I have looked at the following cases:

phanteks Enthoo Primo

Corsair obsidian 750d

H440 - NZXT (nice case, sound dampening but poor thermals)

H630 NZXT (better thermals, no side window

Which of those would be best for my loop and are there any others good cases I have missed? Thanks, Double

Dude they will all be silent within reason. rad space x fan rpm = DB

its what your are comfortable with that counts.

The Enthoo Primo is fantastic.

With my fully under water system, I can only here the pump, and I think that's only because I have a drive bay res/pump combo

Case won't really make a difference. You want as much radiator space as possible and then run your fans on as low rpm as you feel comfortable with
