Looking for the best air circulation.

Planning on building a computer, very confused on how the air circulation will work to obtain the best temperatures and least dust.

I heard from forums that the more fans in the case can accumulate more dust than a fewer amount of fans. But it only sounds right the more the merrier.
So whats the matter here?

The case I'm going to get is the CoolerMaster N300 KKN2 and I have roughly thought about the fan placements.
Front: 1x 140mm Fan
Left Side: 1x140mm Fan
Top: 2x 120mm Fan
Rear: 1x 120mm Fan (pre-installed)

Any good advice to improve my current thoughts?

Whats your budget for this case?

are you looking for a silent case?
is airflow your main priority?
is the look of the CoolerMaster N300 KKN2, the look you like?

I could provide you with some other possible options depending on the above questions :)
