I would also add that if the modification was simply board-swapping or chip-swapping (e.g., an overdirve processor in a PC), then I think that it would be more permissable to undo the swap. On the other hand, in general, I would leave in place a soldered modification. Indeed, such a mod might have been factory original, as I have seen a number of main boards with cut traces and hand-soldered wires snaking over the board. There will be times when the collector can not tell if the mod was "factory" or "aftermarket".
A greyer area is the following: I bought a Tan-case Osborne 1 early on. Later, I had it upgraded with the 52/80/104 column display option and double density disk controller. As a "collector", does one remove the upgrades and have an "original" O1 (and it was used in the original configuration for quite some time), or keep the mods and have a fuller representation of the product's lifetime? Personally, I would keep the mods.

If you are merely a collector (I like to consider myself an "archivist") I
think the modification is part of the historical fabric of the machine,
and changing it would alter that history.
If you're just a hacker, and you intend to continue use of the machine,
then any change you make becomes part of the historical fabric of that
machine.
It just depends on how you look at it.
