I may be able to acquire a decommissioned server here at work. It's only a PII, though (450 MHz). It's a big beast, but has built in RAID and 6 30GB drives. I'm not sure it's worth the space it will take up for what amounts to 150 GB using RAID5. Is a PII enough to serve DVDs over a network? I assume it's plenty of power for audio files.
EDIT: Whoops, it's dual PIIs. Still not sure if it's worth lugging the big beast home.
