Okay, I need some really quick advice! I have a G5 june 2004 dual 1.8ghz with pci-x slots. I am thinking of purchasing this: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3246388&CatId=2697 Will it work? Its standard PCI, but will it work with PCI-X? I tried installing an old PCI usb card and it wouldnt fit properly, so I want to be sure that this will work! Here is a pic of the slots in the G5. Im concerned about the length of the card, because when I tried to put the USB card in, it wouldnt reach all the way to the slot in the back(metal plate thing).
