The server, bizet.nethelp.no, used to be a Pentium-166 machine with a PCI motherboard (Intel 430HX chipset), 128 Megabytes of ECC RAM, Tekram DC-390F SCSI controller (based on the NCR/Symbios 53c875 chip), and about 20 gigabytes of disk space. This server had been performing admirably since 1997. However, the P-166 died at the beginning of February 2004 - I think the greatest problem was simply age and some dust in places where dust isn't supposed to be.
The server is now a Dell Poweredge SC 420 with a 2.53 GHz processor, 1 Gigabyte of RAM, and more than a hundred Gigabytes of disk space on two vinum mirrored disks. The difference between a 166 Mhz and a 2.53 GHz Pentium is noticeable :-) Also, ATA disk technology now has advanced to a point that I see no point in using SCSI for my home servers - this machine is now pure ATA.
The operating system is FreeBSD 5.4-STABLE. I've been running FreeBSD since 1995, and I am very happy with the performance and stability of FreeBSD.

I do a lot of network experimenting and testing as part of my job, so I have a small lab with several Ethernet switches, Cisco routers and similar equipment at home.
