Linux servers

I recently aquired 4 server for $5 each along with another that cost $110 and I have no idea what to do with them or what they can do for me.

The least powerful one has dual xeons at 450Mhz and weighs 325 lbs and is basicaly a mobile rack with lead acid battery backup 3 PSU's 16 (yes sixteen) Hard drives 10 of which are in an external bay.



The most powerfull ones have 16 RAM slots and quad P2's



Give me some good ideas! I may consider web hosting or becoming an ISP for my neighbors

the HD farm could be used for a File server; Massive storage space to retain
1) archives
2) backups
3) large volumes of infrequently access files.

Thanks for the reply but, i have already thought of that. I havent even used 100gigs on my 6month old desktop so I have no need for a power hungry NAS.
