piece it out. if you try to sell whole...you literally are looking for the 1 guy who wants your entire system. i suspect more likely he will look for 'bulk discount' if he exists. In addition, you may find buyers are looking for 2-3 pieces...and then looking to sell on other bits...which again means discount.
If you sell each piece individually...you can optimize each sale for the [higher number of people] who are specifically looking for that one piece.
