i am thinking on getting a G5 at pretty much a steal price and i have a few questions. It is the 2005 DDR2 PCI-E model do i need a external Wifi and Bluetooth antenna? does the G5 have a second 5.25 drive bay? i have a 5.25 bay internal desktop speakers id like to install into my G5 if i get it. Is there a way i can hook a internal USB 2.0 Card reader to a G5? (This will be the replacement to my current AMD machine) i can add the 2GB RAM i have from my computer now into the G5 giving it 4GB RAM i can also install my current 500GB HDD giving it a total of 1.5TB HDD space. can Ubuntu 12.04 run on a PowerMac G5?
