I just bought a 3D Aurora, its not a very 'stylish' case [although with a little touch you can make it very stylish
(see blow) ] but this thing is just un-hear able, even @ night its just noiseless... maaaybe if you like block you'r room for noises and only turn the PC Up you'll hear a quiet pssssss of the air flow, lol.
another two huge pluses:
its a full tower, meaning its rather HUGE so you wont run out of space, never, lol.
its cheap! probably cheaper than any other full-tower in the market.
look @ it, you might even like its looks.
-----------------------------------------------------
if you wonder "how to make it stylish though?!?!"
what im gonna do to it is add it a small side-window above and right near the passive air cooling filter on the side.
once the window is added, add him wire sleeving+some cathodes to negate the blue colors everywhere [probably green wires+red cathode]
Add him little stuff to make it pretty, like a cooler logo for the projector, I personaly added it a HardCano 9 and you could put few cool stickers on the front door lol...
