What would you suggest danger. I of course want a case that deals with dust well. But cable management, quality, and looks are also high on the list.
Personally, I'd get the 690 II. It looks like a really high quality case with great cable management and looks. this
review says that the front panel features a dust filter, but the side panel does not. IMO that's not a very big deal. The top panel also includes a dust filter:http://www.youtube.com/watch?v=Ed4RC6r2NTk
I know for sure that it has a filter on the PSU area - evidence will probably be in either one of those reviews but I haven't checked.
I would say that it looks like this case has decent dust filters - enough to keep your system reasonably dust free. I don't think there's really any case that can keep dust out completely, but as long as you keep the area around your PC reasonably clean and clean out the inside of your computer occasionally, you shouldn't get much dust clogging up your fans or damaging components (I've never heard of anyone's components being damaged by dust though).
All-in-all I'd definitely say it's worth getting the 690 II
