opus only comes from the ms repair factories. it is a board that is similar to the falcon mobos, with the exception that it doesn't have hdmi. this allows them to re-use the cases from xenon and zeyphr systems. it is essentially a xenon with the rrod fixes done to it.
jasper is the next true revision, and actually brings a new chipset to the table.
Any motherboard that will plug into a 175watt xbox 360 power supply is a Opus board. They are all over in stores mostly with lite-on drives and as well they have been coming back from microsoft. I am not sure about a non hdmi opus board. I dont think i have seen one.
The 205watt boards have a square pin in the center of the power plug on the back of the 360 on opus its missing.
