Oh stop being so lazy... just sell it all on Agon and be done with it. No one wants your old crap.
Kidding aside, if the room looks cool and you offer the gear as an option, I think it'd be cool. Otherwise, the chances of this situation working out the way you want it are not good.
Also, if you did get an extra 10,k on your house, wouldn't you have to pay that much more capital gains tax?
Good luck selling it!
