Silverstone CW02 mods + best filter medium + DIY filtration box

[Church]

Women stockings are good filter material because of two reasons. 1) they are cheap, 2) they can be stretched at varying degree by doing what you can get different compromise/level of filtration vs airflow resistance. Only thing that i might not like about them - depending on filter frame you make or way you attach them (eg. by scotch tape) result might look geto-ish. As for few other filtering material airflow resistance, probably already mentioned thread from stickies may help (BTW, am i the only one that don't see images in it anymore?).
