When I pull the cooler off I will, but it might be awhile.

I have not dug into what the various southbridge, specialty chips contain. Perhaps one of them has more easily supported network or sound or something(?).

If for example one was connected to one or two PCIe lanes it might have provided two more PCI slots for lower demanding add in cards splitting the load on the other chip.
Or also connect the XMOS chip to the second 'southbridge' instead of the localbus.
Speaking of XMOS, it sure would have been nice if its xena slot were PCI.

I do like the PA6T. Its kind of a desktop oriented POWER series chip.

I guess cost was a big factor.
