Guys, I have a PowerMac G4 Quicksilver model M8667LL/A, Dual 1.0 Ghz, that I'd like to see about adding an additional USB port to the back of the unit. It only comes with two, one is being used for the keyboard-> mouse, the other I have an external hard drive plugged into. I recently bought a cradle for my Fuji digital camera that comes with a USB cord, I'd like to hardmount the cradle and plug it in but don't want to swap with the hard drive every time I use it or run the cable to the spare keyboard port, that looks like hell. Is this a feasible option to do, and if so, how? Mind you I'm not a computer expert so I'd either need a very basic set of instructions or an technician to do it locally, but first I'd like to know if it's even possible. Any help is appreciated.
