GPS Pilot tracked down some info on PPC Motherboards. "An article on eeNN describes some motherboards that Motorola recently released. They'll fit in a standard PC case thanks to the ATX form factor. They are CHRP- and PReP-compliant. The MTX604-070 has dual 333 MHz processors, dual 100 base-T ethernet, and fast&wide SCSI. More info can be found here. They can be purchased from Avnet Electronics Marketing, (800) 332-8638 (specify "Motorola Computer" as the manufacturer, not just "Motorola"). Or buy direct from Motorola here." Who needs Apple?
