Uses for old HP Server?

I recently acquired an HP G50, 9000 series server. It has HP-UX on it, 96MhZ RISC, 256MB RAM and a 4.3 GB SCSI. It seems to work as well as it did when they made it 6 years ago.
I’m entertaining suggestions for this thing’s usefulness in either my home LAN (fileserver? webserver?) or as any kind of networked device.
