Define "computer fingerprint", please! If you mean a unique identifier
of the motherboard then obtaining this is a simple task. Please
elaborate, though, so the correct code can be provided...

That's what came to mind -- that, or perhaps the serial number(s) of the
processor(s).

I hope Michael elaborates just so we know what the hell he's talking about.
