Maybe you enjoy making 7 backups of your data, or maybe you want to be more of a pirate either way, this is quite cool. John Masone has hacked up a G3 Blue and White Tower to create a tower which is capable of burning 7 CD's at a time. If you still have a need to mass burn CD's then this is ideal for you. It can rip CD's at the drives maximum speed and then is capable of burning to the 7 drives in compressed MP3 or similar formats. The case uses metal caging which has been hacked in to the original tower which now allows the 7 drives to sit comfortably.
If you want a ton of your old CD's ripping then you should give John a shout
