If you're still looking for a leopard disk I have an original I could rip to iso for you
The PPC iMac I wanted to buy got sold right in front of me. I messaged the seller about coming and picking it up, we wrote back and forth about when it'd be an appropriate time, and bam! He took down the page and I couldn't get in touch with him anymore, so I sadly no longer need a PPC copy of OS X. At least unless I find a similar deal, but other deals I'm looking at include original software discs.
