how many fans and placement?

If you have an enermax or another dual fan psu you can ditch the fan in back blowing out, otherwise this setup is perfectly fine for non overclocking.

One fan in front pulling in, one fan(or psu intake fan if you have a good model) in the upper back pulling out.

Thats it, no hurricane no ice cubes, if you dont overclock athlons arent all that special in regards to cooling methodology.

I'd say that something fairly reasonable is:

An intake fan, about 80x80x25 or larger, in the lower front of the case.
An exhaust fan, about 60x60x25 or larger, in the upper rear of the case (generally in a vertical position similar to the CPU's vertical position).
A good quality 300+W power supply with an 80x80x25 or larger fan and intake vents on the underside, drawing hot air off the CPU area. We tend to favor Enermax, but a lot of people find Antec to be good (especially people on a budget).

I personally favor Sunon or Papst for fans. Papst is the very finest quality; Sunon is quite decent for those on a budget.

You can go beyond this with many cases, but this should be sufficient for non-OC'ers.
