I have a g3 beige that currently holds my music collection and older software.. I would like to add an internal CD burner to it. Do I have to use an apple one, or can I use any old dirve? I have a memorex DVD burner that is spare that I would like to add if possible? If I donload patchburn would it work? Also: I have OS 10.1 installed currently- I have OS 10.2 disks availble though....Would my computer run faster with OS X.1 or OS X.2? Lastly: Would adding a 10/100 ethernet card help the computer's internet speed at all?
