Switching RAM should prolly not change the ID, but motherboard, CPU,
disks etc are all fair game. And as long as USB does not play a role,
I can live with _any_ hardware change creating a new ID as long as it is
deterministic and reproducable.
Even though the serve is still, metaphysically, "the same"?
You could take the serial numbers from various bits of hardware, and
MD5 or SHA1 (yes, I know these are cryptographically weak, but
remember the limited scope of the task at hand) the concatenated string.
