The way it went last time was that various systems were supplied to the developer who took on the bounty - there were various reasons for this. As things stand, iMac G5 support may be happening anyway. http://www.geit.de/eng_index.html (read the 'Geit@Home #2 2013' entry) Also, no one has said how much they're willing to put up. The way bounties work is someone makes a proposition and, if it's attractive enough, a developer might take some interest.
