Bigiron 2
Bigiron was phased out at May 1st after a long and productive life. Its successor is on the way, and as I've predicted previously, it's no longer powered by AMD:
I'd prefer to run Debian Wheezy on this newcomer just as on Bigiron and Tungsten, our other workstation, but some software we intend to use may not install on a Debian system. Anyway, I'll post benchmarks as soon as Bigiron 2 aka Osmium is up and running.
