Testing out the First OptiPlex 760

In light of my having stopped making first comments, how about testing the "first" of three Dell OptiPlex 760 series computers instead?
So far, this computer works just fine and seems very stable. I've had it running various things since this video was shot, including the entire BIOS resident Dell diagnostics routine, Memtest 86 and a live Linux distribution on CD. The only thing I've found not to work so far is the optical drive, and I suspect its lens is simply dirty.
All three of these OptiPlex computers came from a hospital.
