Then use eBay. Older Macs get good prices. Those oooooooooooooooooold PowerMac G4s can still run Tiger and probably will run Leopard, so I don't quite see the thing here, rubaiyat. Unless you mean your PM 8500/120 can't run Leopard. But that train has gone when Apple officially declined support for pre-G3 hardware for the _original_ OS X more than half a decade ago. The other oldish but OS X supported hardware runs 10.3.9 AFAIK, and that means it runs most newer software. No big.
