This is the Dell Consumer Hardware Agreement. I realize no one reads these legal papers, heck I don't either but it is a service agreement. Pay special attention to the PDF item 10. I am including it below. I have indicated in bold the applicable portion. "10. Parts and Product Ownership. All service parts removed from Customer’s Product and any original products for which Customer received a replacement product become the property of Dell. Customer is obligated to pay at the then-current standard Dell price for any service parts removed from Customer’s Product and any original products for which Customer received a replacement product that are not properly returned to Dell by Customer. IF YOU FAIL TO PAY DELL FOR ANY PART OR PRODUCT, THEN DELL MAY CANCEL THIS AGREEMENT, SUSPEND YOUR WARRANTY AND/OR SERVICE SUPPORT ON ANY DELL PRODUCT YOU MAY OWN UNTIL THE APPLICABLE AMOUNT IS PAID, AND/OR TAKE OTHER LEGAL STEPS. A suspension of warranty or service for failure to properly return a part or product will not toll the term of your warranty or service, and such warranty or service will still expire in accordance with its original term."
I sent in my out of warranty Aurora R7 to have the motherboard replaced. I am wondering why I am not given the option to have the old parts sent back to me? The old motherboard and or any other parts that were replaced. Are these not mine? Do I lose ownership once I have Dell replace something? If so, where in the agreement is this? Thank you for your time. 
How to get my old parts back after repair?
