One of my happiest roadside Mac discoveries was finding a complete G4 cube system for... get this... $25! So, now it sits sadly in the spare room used by the occasional houseguest for checking email. I want to continue using this super-cool little gadget, but for something more... productive. Also, I found out well after buying it for a song that it was owned by one of the young sailors who Al Quaeda took from the USS Cole in 2000, so I'd like to not kick it to the curb too fast. What are some ideas? I thought of maybe a media server?
