Yes, that or a slightly faster one. I like the ones where we went with gigabit ethernet (2nd gen G4?)

Not without a rom change.
One of the big problems was this was the first machine with tightly tuned ddr memory and there
was a lot of magic performed to get it reliable.

It's been a while, if it's 1.25, this may have been a next generation G4 that wasn't so power hungry.
First gen MDD was bad.
I was off of G4 and working on bringing up G5 by that time.
