I have a 500 MHz Cube with a GeForce3, 1.5 MB RAM, 80 GB Drive, the stock CD-ROM/DVD-ROM, running whatever is the most current version of OS X. I would like to send a bunch of old CDs to I-Tunes and then burn CD(s) to put in the car. As you can see, I have modified the basic unit, but I really see no point in adding anything more to the interior of the Cube itself. It runs with a couple of extra fans above and below and performs ok, as is. I know there are a lot of external burners out there, do they play nice with I-Tunes, or are there problems with copy protection. Thanks, Dave Iverson
