I added another quad core machine to the farm. Its the same as the others. It will replace an old P4 (when the P4 finishes off its current work).
This latest addition brings the farm up to 4 quad-core machines. They are all Intel core 2 quad Q6600's running at 2.4Ghz with 2Gb of RAM.
The new machine is on the bottom at the front and is called Luke Skywalker (in keeping with the tradition of naming them after Jedi knights).
