I have the urge to install NetBSD to a power mac g4 or a mac pro g5

I have the urge to install NetBSD to a power mac g4 or better a mac pro g5 and use it as my daily driver
I'm a Boomer !

Read that G5 are hard.
But if you install it on a G4 let me know
I have a nice PowerPC Macmini in need of some love
