A friend needs to identify a G4, the only photos she has of it show it's the original case style and the keyboard isn't the pro, it's the first USB model with a power button near the delete key. The mouse in the photos is 3rd party. She just wants to know if the machine is worth shipping from her parent's house across the country or if they should sell it in a yard sale. My guess is it must be yikes/sawtooth, around mid 2000, but perhaps gigabit or digaudio might have come with this keyboard as well? I'll try to sell her on an itunes/file server for her macbook idea, but i'm not sure she'll spring for a HDD, memory and shipping. TIA to all keyboard experts.
