zhulien explicitly referred to "other system's G4s" in comparison to "the Pegasos 2 G4", so he clearly didn't mean any Pegasos 2 by "other system's". That's why I answered his 2nd question by giving him links to overviews about the G4 line in general.

Apart from that, there were a few Pegasos 2 delivered with not the 1.0 GHz 7447, but with 1.4 GHz 7447A:

Really? ;-)

thanks all, i didn't know there were different G4s...

@ Andreas_Wolf

Ok, I meant active :)

I am not sure those 1.4 cpu cards ever shipped to end users?

Gunnar "BigGun" von Boehn of Greyhound Data is a developer. I don't know about the "Pegasos 2 users" itix wrote about. Taking into account that a Free Developer Workstation is obviously aimed at developers, you are probably right that it didn't ship to end users initially. But developers can very well have sold their machine to end users by now.

Thanks all, but very expensive shipping on the items.. I will find some with cheaper shipping :)

I am using an SNE heatsink and fan:

Check the MWF404ALCU half way down the page.
It's actually a VGA or Northbridge cooler, fits perfectly
and very quiet. The fan in my case and PSU fan creates more noise
so I don't see any point in passive cooling.
