There's a really cuil set of photos showing the Large Hadron Collider being setup in Europe. Very high tech stuff.
Just a little bit down from the top of the photo stack is an image of someone way down the aisle in the server room. You get the idea that there are just racks and racks and racks of servers with a mind for effective use of power consumption, space utilization, heat and all the other green elements.
The person at the end of the aisle is working on a server. They're sitting at a workstation, typing on a keyboard... looking at a monitor. Not a slick flat screen, but a huge honking cathode ray tube monitor from 1994! Hah! That thing probably takes up the space of three or four servers and gives off as much heat!
