How important/useful is having dust filters in the case? I just bought a Corsair 200R and when I got home, I realized it doesn't have filters (I looked at so many cases the last 2 days I guess I got some of them confused). People seem to like the 200R. I also looked at the Fractal R4 but I don't like having the ports on top since I typically keep the case on my desk rather than under it.
Well the dust filters... filter dust. So if you don't have any, it's not critical, you'll just have to clean out the insides of your PC more often.
The 200r does have filters, only on the front intake and psu intake though.
