Debian can be installed on G5 (although the latest stable Debian 9 "Stretch" isn't supported, what you can do is install Debian 8 "Jessie" or the unstable branch "Sid") [1]. Also note the PPC 750 and PPC 7400, used in the Mac G3 and G4 computers, are NOT affected by meltdown & spectre, so if you want a secure desktop, try Debian on G4 [2].
