Yay for triple posting....

(don't worry guys, I'll go lower my post count )

Anyway, for the "Metal Mesh" filter...do people mount that on the outside or inside of the case?

That is:
1) FILTER | CASE PANEL | FAN
or
2) CASE PANEL | FILTER | FAN

I know how the rest get mounted, but this one seems to be able to go both ways, not sure which people do more.
