No, negozio...
La loro risposta:
I don't believe we advertise either case even having a top filter anywhere. Technically it's not a filter, it's just a finer mesh screen, and it's not easily removable (and it's somewhat restrictive). Since the top area is used for exhaust it's better not to have it for improved airflow out of the case.
You can see pics and more explanation of the filter here: http://forum.mechlivinglegends.net/index.php?topic=17803.0
