You have to follow your heart on this , if you choose to part it out as has been said you could make a lot of people happy and recover a fair bit more money .
You can look at it that you are wrecking a complete bike and i know that seems wrong
but on the other hand by sacrificing this one bike you could potentialy get 2 or more bikes or projects finished with parts from yours
You will enevitably be left with some parts though and my suggestion would be to offer them to the buyers of the parts you have sold for free or a token payment or trade .
This way you have done all you can to find homes for all the parts so you have a clear concinse
if nobody wants the left overs then dump them
its not like you haven't tried to do the decent thing .
When you part out a complete bike there will always be the knockers
but its the same knockers who wont pay a fair price for the complete bike , so fork em
Good luck
