Would it suck a lot of dust like a vacuum cleaner? :)

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.

Most power supplies suck air in through the bottom (or top) of the unit
and exhaust it out the back as their cooling strategy. 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.

I'm talking about no hole at all. 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.

Just keep your local area free of dust. If you don't like
housecleaning, hire somebody.
