I don't think all the shards are there, I think its roughly 1/2 to 2/3rds of the needed shards. I don't think gluing it back together and molding it would really be an option. There's lots of little cracks in it so demolding could possibly break it up even further. It was made with something like Smooth-on Smash Plastic or some other brittle clear casting resin since it was a 'break' model. I'm thinking of getting a pelican case for it and putting the damage side down and rigging a small LED light source with a toggle switch to the side of the case.
I have 2 of the ZPM's from the SciFi hero run, at least having this one lets me accuratize those as much as possible. Biggest thing I noticed right off the bat is that they did use black silicone to do all the lines. The fan repo ones have that all molded in and has to be painted a semi-gloss or flat black by hand (lots of masking). I haven't measured the dimensions to compare yet... honestly I'm not sure where I stashed the SciFi Hero repos atm.
