I see a lot of Powermac G5 twin cpu for sale with a low price tag (50/100 euro). Is it worth to try to build a FrankenXenon? What are the possible benefit, more than a rgh xbox360? Is it compatible with retail game? Can I use the extra cpu power/ram? Can I connect more sata disk and use them for xbox files? Will aurora/fsd/homebrew work? I know about the xenon wiki but I wasn't able to find those answers.
