Really well spotless inside :)
Did have an issue with asus ai suite 3 and a setting in it has a anti dust that was reversing the fans so it was sucking air though the exhaust and pushing air on the intakes on startup and every 2 hours :/
Well I got rid of ai suite 3 because the sucking in on the top intakes was pulling over night dust into the case,
As far as I've noticed the default bios setting don't do that annoying feature

So I had to restart the time it takes to clean the filters
I also reversed the psu so it pulls air from the bottom instead of sucking air from inside the case and of course added another filter there too which there was already one for the 1 bottom intake so it just got bigger :)

Front grill was more fun to seal than the bottom filter,
The removable front panel is not all that tight so I had to add puffy tape to edges of the frame to get a tight fit
Love the lighting made it easy to see where it was not a snug fit
