I would just come back and offer him scrap value for all of those servers. They are worthless for anything but scrap at this point.

If he doesn't want to take it don't budge. When he can't sell the servers then he will finally come back to you and say alright lets do it. That is when you tell him you will come pick them up for a fee.

If he wants to play that game, play hardball with him. You can't win this game by being mister nice guy.

Off topic, but I have a customer who every time he sees a car for sale by owner he immediately calls the number and offers the people 1/3 of Blue Book value. They ALWAYS balk. He tells them that is fine, just keep his number and if they change their mind the offer is always on the table. More often then not he gets the call back and he buys the car, puts it on the corner lot down the street from his house for blue book value and bam. Sold in less than 1 month.

Don't let these guys push you around. Do your homework. For Dells if you get the service tag you can go to support.dell.com and find the initial configuration of the device. Learning server hardware takes years of time and effort. It is not for the faint of heart. As Olddude stated he spend a ton of time and effort getting to where he is at and there is no better teacher than the school of hard knocks.

If anyone comes across any servers less than 3 years old feel free to hit me up. I am always looking for new equipment.
