So, I picked up a Mac Mini G4 for a good deal. It is a base 1.25 GHz model with 1 GB of DDR SDRAM, Pioneer DVD-R/CD-RW, and Samsung 128 GB SSD. The solid-state volume is divided into equal partitions for macOS 9.2.2 and OS X 10.4 Tiger. 

And yes, the Mac Mini G4 can boot macOS 9 natively with some help.
