What are the oldest PCs you still use on your network?
Just a general question really, I see there was an old thread about oldest production server too. Would be interesting to hear what sort of machines you all manage to keep going, and in what role. Here, I have:
Oldest servers: 2 x Dell Poweredge 2550 (2 x P3 950MHz) - backup DC and Successmaker
Oldest student desktops: AMD Duron 850 with 512MB of RAM - they actually run really well (nothing less than 512 now)
Oldest staff desktop: AMD Athlon 1333 with 512MB of SDRAM (undergoing maintenance!)
Surprisingly small amount of trouble from the older stuff, as they tend to be put in lower use areas. Have had loads of P4 machines give trouble though, usually dying onboard LAN and IDE.
