Silverstone CW02 mods + best filter medium + DIY filtration box

[jalyst]

90%+ of the dust that gets inside a case comes from the fans.

Of course, the intake fans to be specific.

But saying that positive pressure prevents dust from coming inside a case is plain wrong.

Sorry but I'd still have to respectfully disagree there, the laws of physics must prevail
But you're entitled to your opinion, I'm not interested in debating this point further, too OT.

I misread your first post...

You probably didn't with your 1st posts, but it looks like you have this time.
Since your 2nd last post I've substantially amended my OP, so that my goals are more clearly defined.
This thread is (in part) about a filtration box for my HTPC case.

I'm also looking at getting a HEPA room filter.
But that's for separate reasons, & not something I'll get anytime soon.
Try re-reading & adding your thoughts, if you have time.

Thank-you.
