need help on best comp fan and setup for air flow

[heyty4thehelp]

I'm thinking of https://pcpartpicker.com/part/rosewill-case-fan-rfa120wl

I'm looking for around $5 fans

that was best one I could find for the best price and free shipping.

Also I have space for 2 fans in front/2 in top/2 in botton/1 in back

If I have 5 fans, which is the best place to put them and which to pull air in and which to pull air out?

There is no such thing as a good $5 PC fan, but I admit that Rosewill fan doesn't look bad. For $5 you can't do better. Buy those and do the classic arrangement:
2 intakes in the front
1 intake on the bottom
1 exhaust on the back
2 exhaust on top

But you probably do not need that kind of airflow, so feel free to just do:

1 exhaust in back
2 intake in front

This will keep the air pressure just a bit higher than normal, helping to keep dust out.

i was gonna buy 3 fans and try to do 1 back/1top/2front/1 bottom(think bottom is worth it? isnt that gonna suck up dus?)

or should i just buy 2 and do 2 front/1back/1top?

dont need any fans on the side?
