I think Kjetil is right here for most situations. There is some doubts
whether a top mounted fanless psu is better then bottom.
Anyway, the choice seems to be the p183 vs Factal design R3

It's hard to judge, not having the cases here, but to me it looks like
the p183 is HUGE... Qua looks and height I prefer the R3, but I'm not
sure the performance will be close to the p183.

I'm just talking out of experience. The PSU is usually the noisiest part
in a computer if its heated, and if you put it at the top, especially
right above the CPU, it becomes too warm. I avoided this problem in one
computer I build (an antec SOLO case BTW) by replacing the fan in
the PSU so that it pused air towards the CPU instead of the other way,
but the easiest way to avoid PSU noise is just to put the PSU
at the bottom.

Ok, but it would be nice if you could provide some sources which makes
clear that and why the bottom PSU approach is better.

Thanks.
I didn't see scientific sources which confirms that the 'PSU on bottom
approach' is better ;)
I was thinking to follow this approach

It just needs one fan...
Bad design. He says himself that:
"The dedicated intake duct ensures that the PSU fan never ramps up unless
absolutely needed. In actual use, it should just about never ramp up
except
maybe in very hot weather under long term high load conditions."
"Long term high load conditions" is something you probably
experience when working with audio. Even just watching a web
page with flash cause high long term CPU usage. There's nothing
more irritating than fans suddenly ramping up.
