Power max G4 and power G4 cube

[Finleyw]

Hi I've got lots of my dad's old apple hardware with G4 cube and the power max G4 with two monitors and some other stuff and I don't really know where to start to if they are working as I'm looking to sell as they have just been sat covering dust.
Any help would be appreciated

I would get it all setup and see if it runs first. With it setup and running take some pictures and post it in the flea marketplace. There will be a collector I am sure interested in a working G4 cube.
