It looks kind of like a filter, if it is, which direction does air flow through it :)? Sorry for so many questions,...

I dunno, mine did not come with a backplate. Was it supposed to?

There are several articles on hd suspension / isolation with foam. Also you can search the forums for "suspension" and get plenty threads.

Do you still sell the DIY kit? I am unable to clickthrough the "configure" link on the productpage.
