Good news, the keyboard started working. Now I can go all around the BIOS seup menu and find I have more questions.
It seems to recognize the hard drive - but since I'd normally format the hard drive from Windows, but have a USB to install Windows to that hard drive, we have a chicken and egg problem.
I have to assume the USB knows how to deal with this and can try that.
Then that leads to - what else do I need to setup? What about 'BIOS updates'? Does this MB have any built-in wi-fi and if so how to set it up, if not do I need to move the ethernet cable from the old PC to this one for connectivity (figuring out how to connect ti hardwired is a whole other issue - I have a second cable but need to get a switch device I guess).
If I find one of the RAM sticks is bad... bleh, guess I'd have to see about buying another of the same type, hear mixing them isn't good.
