  Two things come to mind here.  The first is, that if
memory serves,
 not all of the cards in the original XT were made by IBM.  I'm pretty
 sure that 'Original' HD controllers were made by Xebec, for example.
 The other is, that in other things generally considered "collectible"
 (such as automobiles, for example) it is considered acceptable to
 have some non-original equipment installed, provided it is correct
 for the period (and that the added stuff in of itself is historic).
 But I think this only holds to a point: the system board and power
 supply would probly best kept 'stock', but one of those Quadram 8086
 add in boards would be definitely cool, for instance. 
It's interesting that the collecting of computers will be held to the
same standards, protocols and preferences as those in collecting cars.
