No offense but the experts and the cooling crowd completely disagree with your theory. Bring more cooler air in a path that leads it past hot equipment and out the back and top to where the heat rises. Positive pressure in the case with filters over the intake fans to reduce dust.
If you are responding to me, dust has nothing to do with your computer. Dust is dependent on placement. Also your computer won't sound like a jet about to take off, which is extremely annoying.
As far as cooling, simple physics can solve this one. Your Comp produces the heat. All fans do is regulate ambient temp inside of a case. Mitigating core temps depends on hardware, i.e. having better heatsinks, PS, etc. Fans are simply auxiliary.
Yea, fans are nice, but the reality is that a good topline copper HS and PS will outperform a bunch of case fans all day every day.
Edit: God, I'm a nerd. Wait... I'm only "technical...," which makes me cool.
