Here is my Seti Farm. Not much to see except some pretty blue lights and a tangle of cables.
You can see the 3 quad core machines that do most of the number crunching. There is an old Dell on the left of the table. At the bottom is an ancient desk fan to help with cooling.
The 3 quaddies have names of course. Going from left to right they are Obi Wan Kenobi, Yoda and Qui Gon Jinn.
Current BOINC projects are Seti and Einstein.
