I am still on the search for a case which could help reduce noise of about 10 hdds and sofar the Cosmos II seems the best candidate... I wonder how well the coming 900d from Corsair will be in that aspect ?
I am still monitoring this topic, for the same reason :).
I think the Cosmos II is still better than the Corsair 900D for a huge amount of drives, I have not added the Corsair to my list.
But let me tell you what I did
put on my list!
The Nanoxia Deep Silence 1 case:http://www.nanoxia-world.com/product/1/1/Deep+Silence+1
Which from the outside looks pretty classy and stealthy black.
But check out this amazing feature:
So while I was daydreaming about that case a while back I opened MS Paint and imagined what you could do if you can buy some extra HDD carriages
(Using B instead of A could leave enough space for a decent size GPU.)
Isn't that beautiful? :D
Plus three 5,25" bays still empty, where you can put a 4-in-3 mount or even a 6-in-3 (if you count 2 SSDs) like this Lian Li kit
. My edited picture makes it look like the wrong amount of drives, but from the original pictures you can see that each full stack is 8 HDDs, so two stacks + a Lian Li kit is 8+8+4 HDDs (and 2 SSDs). So total 20 HDDs and 2 SSDs :D.
Of course with 15-20 drives this will not be extremely silent :P. The drives are mounted on rubber grommets, that helps. The rows of HDD brackets is what enables this crazy number of HDDs, but it also blocks a lot fo the airflow from the front of the case to the rear, so you will have to try out what works best for that.
Other good news is that Nanoxia will release two bigger cases in the future :). The first one will be not much bigger than the DS1, after that they will present a really huge case. All cases will be designed as silent cases. But that will take time.
So for now, the Nanoxia Deep Silent 1 is on top of my list :). One other very important reason for that: the Deep Silence 1 costs €100 and the Cosmos II €300!(SPCR topic about Nanoxia Deep Silent 1.)
