Good uses for old iBook?

[Jim Soriano]

So, I've replaced my daughter's original iBook/Blueberry/G3-300 with a 
new iBook/14"/G4-1.2G.

Anybody got creative ideas on what to do with the old system?  It's got 
the original 3.2GB drive and 288MB RAM.

My initial idea was to keep it running OS 9 and use it as a networked 
Postscript RIP for our Epson Stylus 3000, but it will sit idle a lot of 
the time doing only that.

Another idea would be to put it downstairs next to the big ol' A/V 
system, slap OS X on it and use iTunes to access my music server over 
Wi-Fi, then pump the audio output through a external USB audio 
processor like Griffin's iMic into my amplifier.  Do you all think the 
iBook has enough horsepower for that?

Other ideas appreciated.

Regards,

Jim
