Nice gesture and good heart OP. I promise you this though. People are shady. It will end up going to someone that really wont need it or just turn around and sell it. These people saying they will fly out to come and get it. They don't need it if they can afford to do all that. You should disqualify them. Funny to read "oh my wife could use it" "oh my 3770K is on its last legs" REALLY?
You do realize that there are very low cost options for flying these days? Cheap enough that it is more costly to drive than it is to fly sometimes.
