I'd set most fans, front and side to intake with only the PSU and maybe one at the back, out (depending on GPU-fan). This will not only eliminate dust intake and reduce noise but also improve the circulation in the case as showed recently by Silverstone: http://www.youtube.com/watch?v=Qe-2ZqmS ... re=related
Also, too low an air-pressure in the case won't leave enough air to be sucked through the PSU, causing over heating there.
A negative pressure can never create less hot-spots tan positive as they work in the same way, only in reverse. Simple physics though will proove thata positive pressure will leave more air (and heat) to be moved by exhaust fans, thus creating better cooling. It's also possible that a lesser air pressure will conduct heat less efficiently as well as there are less particles to absorb the heat within the chassis but with the relative pressures involved we're talking theory here!

I've got 6 of them in a P182 turning around 900 RPM and I can still easily pick out drive seek chatter.

I'm using the fan headers on my Abit IP35-Pro. Between the BIOS and the uGuru software I can set individual temperature/speed profiles for the CPU fan and the 5 chassis fans using 1 of 3 temp sources, the CPU, the PWM circuits, or the internal case temp.
