This one has no real significance, but it is useful enough that I can actually put it to use rather than let it sit around as a museum piece.
Processor: Intel Pentium III @ 750 MHz (although the service tag specifies a 1.2 GHz part)
RAM: 128 MB PC100
12 GB IBM Travelstar hard drive
Display: I don't know or care.
It's well used, the side of the display housing is bent, the hinges are weak as well.
OS: Windows 2000
Current status: Used for a couple of experiments here and there.
