Looks, i'll opt for cm stackers.. but if you ask me to choose, i'll choose v1200. don't know why. i love big casings. don't mind the looks. cause you're not going to stare the whole thing all the time. as long as it provides cool case then its oke.

if what you all mention that cm 830 gets dusty. means its good in circulationg air. thats not a bad sign.. hmmm
