In Linux Under the Desktop I had said:

What is Linux under the desktop? It’s the practice of sticking a server under your desk to get the job done…

Over time, these machines become useful, or even critical, and you need to move them into the server room along side all of the Windows boxes…

We just moved two Linux boxes out from under the desk and into the server room… And will probably put one more in there. Progress… it just takes time…
