azdesign Top filter is useless because it cover holes intended for exhaust. Bottom filter still useful.

bonehead123 Well, finally, case mfgr's are starting to include USB C connectors on their front panels, finally.

bonehead123 Not a bad looking case per se, but nuthin new or exciting either :D

In this case both are useless if they get clogged with dust and restrict airflow even more, but I think that's the whole point of dust filters.Top ones were life savers at one of my workplaces. Most of their later PCs have Aerocool Aero-500 chassis, which has a top mesh on magnetic strips. People would use their desktops as "underdesk shelves" for their lunch, dusty slippers, phones, keys etc., so when it comes to maintenance, all I really need to do is take the mesh, blow some compressed air through it, wash it and put it back on. The insides are usually as clean as my cat's ass.One employee was stupid enough to take the cover off (for the sake of better airflow, as you've mentioned), and the next thing you know a small metal staple from his work documents fell off the desk right into the venting hole and shorted the motherboard. All USB ports died, Z97 board had to be replaced. It's a stupid and unfortunate coincidence, but if the filter was in place, there wouldn't be any of that mess.Another dude threw away his dust filters entirely (they were too dirty). His PC got clogged within 3 months, cause the entire office floor has carpet and the cleaning schedule is irregular at best.It's better not to have any vent holes at all, than turning your PC into a vacuum cleaner.Yep, that's a big plus. I used to think that it's not critical, but now I use it daily on my AsRock DeskMini.The price tag is definitely new and exciting for an SFF.
