How to dispose of your system?

A lot of us are getting to the age where  we may start thinking about what will happen to our precious systems when we’re gone?  Will they be sold in pieces, breaking up the synergy we’ve worked so hard to establish? That seems to me to be criminal.  
What about trying to sell the whole system, kit and kaboodle, maybe to a member of this forum? Would anyone, perhaps a novice, be willing to pay for a very finely tuned instrument? 
If the system cost say,  $35K to put together, what would a fair price be?
