A G5 PPC Mac can not go higher than Leopard 10.5.8.
Look for a black retail install disk on eBay or Amazon.

thank you very much for your hint!
Should a Mini Mac installation disk 10.5.6 work as well? I tried but the installation was prohibited although in the installation requirements a G5 is mentioned to work with.

Like Niel says, it won't, because those disks are machine specific. Also, it would be a breach of the license agreement.
