Hi,
In my new case ,BTX compliant, case,
The psu is in a seperate bottom duct, and expels through the rear,the inlet for the psu fan is via base inlet,
my cpu fan, akasa 965, are extracted through the top case fan 120mm,
the memory, gfx card, and northbridge 60mm fan, are all fed by 2 x 120mm case side fans, and extracted with a rear 120mm fan,
the hard drives are cooled via a front mounted 120mm fan assisted inlet,
all fans are temprature controlled with a homemade fanbus with temp sensors, with thanks to spodes abode website posted elsewhere in these boards,
And you know what! it hasn't made any temp difference to my case or components whatsoever over an ATX case prevoiusly used !!!
But it looks different and sounds like a farrari F1, but i'm tone deaf anyway,
Which as a consumer is your choice,
My PC is stable, But I don't know about ME, hehe
cheers
