Great and steady case, I have cut a transparancy film so i have a window behind the honeycomb window. That keeps a lot of dust out. Only problem with the case is that the LED is right on top of the part where it's after. You will always look right in to the LED instead of the light of the LED. I thus have put a black sticky paper over the LED so it puts only the light in the right direction (the case) and not my eyes!
In the points against the case is the nearly impossible way to clean the front filter. Solution: Turn PC off, get your vacuum cleaner. You'll know the rest.
