Thank you for your interest in Intel products.
I understand you are trying to purchase couple of Intel® NUC's as second-hand.
My recommendation is to contact an Intel Authorized Distributor around your area and try to get new products. You will be covered for three years on the warranty.
I regret to inform you that if you get second-hand computers, they are not covered under warranty in case of any failure.
Thank you for your time.
