That is a good price for a registered MorphOS2.x system. All the buyer would need to complete it is any USB mouse & keyboard, plus a monitor, and they would have a nice, small footprint, fast, MorphOS2.7 system.
I have a 1.5GHz G4 MacMini with registered MorphOS2.7/MacOSX10.5.8 dual boot and love it. Really like the Amiga compatibility (runs lots of original Amiga 68k software without needing to load EUAE + PowerUP/WarpUP software), the speed, low power consumption and small size.
