What alternate OS for PowerBook g4?

[Equis]

So I found a free, perfectly working PowerBook G4, 512mb system ram, 1.4 ghz power pc. I've been looking around, looks like you can load some kind of Linux in it , which would be the best?

Puppy Linux, and you maybe able to par down Gentoo to run on it....

Ubuntu 12.04 for PowerPC - probably your best choice depending on your skill set
Debian for PowerPC
YellowDog for PowerPC - based off the redhat distro

Solaris 2.5.1 if you want to go hard core.

Is it that you dont want to run the mac os, or that you don't have the disks?

Slackintosh, but you would probably have to know Slackware pretty well.

Ubuntu is very newbie friendly.

The last version of OS X to support Power PC was 10.5.x. Apple doesn't really announce EOL, but I don't think they've issued a security update for 10.5.x since 2012. I don't there's any inherent OS vulnerabilities in 10.5 that are known, but it's probably safer to run Linux so you can just recompile your own kernel as patches are issued.

Apple released a "secret" update that disabled Java 6 on PPC and Java 7 won't run on them. 10.5 was a horrible OS anyway.

OpenBSD.
FreeBSD if you don't care about security.
