Stealth rig at work. Only 1400 kh/s for now. A 7970 and a pair of 5850's, soon to be joined by a 7950. That stand is an old PictureTel unit I was given that I gutted. Tons of room in these things and designed for cooling. There's also a Logitec sub in the bottom compartment as the Unit's "Clark Kent" theme is my jukebox/workstation.

Nice design. But I hope you are not stealing your employer's electricity, that would be just asking for trouble...
I did the very same thing at my work around a year or so back, it was great experience for the farm I'm running now.
It's a very good thing you've hid it, and if you haven't already I would not tell your coworkers what exactly it is you are doing. In a year, they may just be jealous haters, saying you've got preferential treatment...
Here is 1/3 of my farm that I've managed to get deployed so far. My rigs love the environment, it stays a steady 60 degrees or so, and my cards stay around 65-70c at the most.
There are 12 290's, 6 280x, and 6 7950 in this picture. Not shown are 12 more 290s I am "proving out" at home, as well as a few other misc cards.
My net hash rate is ~30M
