I would say its Legit but I can't say its completely stock. The PU's and Rings look wrong. Maybe they were so rounded and open back in 2002 but to me they look wrong. There seems to be too much space around the PU's too - maybe because the Rings have been changed (from white PRS rings to black generic rings for example) and/or the Pick-ups too.
To me, something doesn't look right here so I would want to look it over, try it out and if necessary, even look under the PU's to see if they are actually PRS PU's. If not, then I would also want to look under the cover at the electronics, see if the soldering and wiring was done well.
It looks tidy enough, not that I like 'blue' guitars personally (I know its not me buying etc) so I can't 'enthuse' about it but from a purely objective point of view, the guitar looks to be in great condition otherwise. Some very minor 'dings' on the Headstock and maybe one by the Trem too (could just be light reflecting off the body) is all that I can really see in the photo's and from what I can see of the frets, they look OK - maybe some issues under the strings that I can't see and/or levelling issues but from these shots they look good to me.
If it wasn't for the Pick-ups and/or the Rings, I would say that from the provided photo's. this looks to be a legit and good condition PRS CE Custom 24. I would still try and check out the PU's, PU Ring and wiring - they may have swapped them out.
