3x Dual Xeons 3 GHz with HT, 4 GB RAM...

Challenger, Atlantis and Blackbird in that order, running Gentoo happily :)

 

They were all Dual Xeons with HT, 3GHz, 4 GB RAM 2x 73 GB SCSI HDDs. Challenger was our internal webserver,download mirror, Gentoo rsync & distfiles mirror. Atlantis was our gateway box handling DNS, DHCP, iptables and Blackbird was the sound encoder and was the laziest of the three.
