i have a couple more, although these were a couple years ago, and they belonged to work. please excuse the cleanliness of them, i was in a very sandy place far from here.
First, some sort of Dell desktop. no memory of the specs i just know they used 2 video cards for 3 total monitors. XP Pro.
Second, 3 PowerEdge servers. one dedicated for network monitoring (the nice piece on the wall with Solarwinds running), one dedicated IRC server, and the 3rd just for regular admin use. all running Server 2003.
4 HP Proliant (G6 i think). 2 DNS, 2 Exchange. all running Server 2003.
2 PowerEdge servers for DNS, 2 IBM servers for Exchange. everything on the left was for satellite equipment. all running Server 2003.
4 PowerEdge servers. 2 for DNS, 2 for Exchange. all running Server 2003. everything on right is for another satellite setup.
