Machine returned error of "no media present" which means hard drive failure.I contacted Amazon support within the 90 days of their support.  they told me to send a ticket to Beelink through a provided link.  Amazon said they would follow up but never did.  I submitted ticket to beelink but never heard back.  Now Amazon wants me to pay a restocking fee.note to self: do not buy computers on amazon and do not expect support from amazon within 90 days because this is the support model: "Yes, we do have 90 days coverage, the first 30 days product falls within our return window. The next 60 days is to help customers with troubleshooting or to referred the manufacturer/seller to claim warranty."
