You talking about a dust filter? I was talking about a regular hole! The old design (power supply at the top) should be more tolerant to dust. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

If the air is dusty it will suck in the dust also. Most time the air comes from inside the case, so the air comes through the case intakes. Most cases have a screen on the intakes. Short answer: it probably doesn't matter where in the case it is, but if you keep your case on the floor and never clean your screens or blow out the case then it might see a greater than average flow of dust.

The PSU in my P180 gets its air from the front of the case, the same as if it was at the top, except its /nearer/ to the source of incoming cool air, which should be better for it. -- SteveH
