I have a similar AeroCool case (the ExtremEngine 3T) and it's quite nice. The machining isn't perfect or anything, but it has a really great airflow design and the finish is nice.
I would suggest if you get that case to do what I did and mod it with a top exhaust.
Other options would include the Antec Nine Hundred and P182 (it's not out yet but I think it's about to be).
The airflow on that one doesn't look nearly as good to me... just doesn't seem to be in the same high-performance class as the other cases I mentioned.
EDIT: I know you listed the three brands you like, but this case looks really awesome so I thought I'd throw it out there:
The front doors are brushed aluminum so that helps the look a lot. The rest is steel with a nice flecked black paint on it. A couple parts are plastic though, so I know what you mean.
The NZXT looks cool i guess but the chassis is aluminium and the front panel is plastic. Dont know how strong it would be. I can get that one,
not sure though.
I can get the zerodegree and aurora cheaper.
The aurora is fully aluminium incliding front panel and door.
Not sure about the zerodegree I know the door is aluminium.
Id the raidmax smiliodon that bad? seems to have doors that open nicely and a removal md tray. But the air flow doesnt seem that good.....
