Yes you're right about Stacker.Of course it's a better case but it's price is double than Aerocool case.
Yes the Stacker is not cheap but comes with a boatload of goodies

I bought mine in 2005, choosing it over the P160 and I'm very happy of it for its flexibility.
In the box there are 2x120 mm fans which are not the quietest in the world but perform (airflow and noise-wise) better than the Antec TriCool, and are only slightly noisier than the Aerocool Turbine (which is close to the Nexus); it has an 80 mm fan, too, it's not bad but you'll probably end using it somewhere else.
You'll also given the option of rubber feet to dampen vibration or wheels if you want to move it easily (useful, it's heavy!); it has filters for all intake vents (except the bottom and right side), comes with a soft-mounted, 120mm-fan-cooled drive bay whose position can be adjusted at will.
It has easy, snap-on mounting for all 5.25" units (including the 3.5" adapter) and a front panel with 6 USB, 1 firewire and audio connectors, that you can put
on top for easier access.
And if you get a good, flexible case, you won't need to buy a new one for quite some time

And this case also can support ATX and BTX mainboards in case you didn't noticed the interior design of the Aerocool case.
I don't think BTX will have much success, anyway. There is another reason to flip motherboard, though: if you have an intake duct, and want the intake vent to be as low as possible.

And who needs double PSU in their configurations?
Extreme watercoolers

and systems which need to power up a large array of powerful devices (maybe disks and/or peltier cells, TEC coolers) While I agree with you that double PSUs shouldn't be that popular, Antec will release a case which has this feature

I just want to know about silence capabilities of this case and not the other extra features that more expensive cases have.
The mesh on the front is good for airflow but leaves open space for noise to escape. IMO a system should be quiet because it produces little noise, not because it's sealed, but if you want extreme quietness you might fare better with another case.
Otherwise you could just close down the front of the system, leaving only a minimal vent for disk cooling, or close it all if you put the disks in that other tray it seems to have. Just use those three 80mm fans on the side for air intake (even if I'd prefer straight line airflow with front intake)
