Bought this unit in Feb 7 2023, died in July.  Comes up no bootable device.  Very disappointed as we lost all data on it.  Replaced it with a new system, and this one has been setting on a shelf.  Today, while cleaning out the shelves, removed that NVMe SSD 512G.  Plugged it into my NVMe adapter, and sure enough, the drive was dead.  Order new SSD drive and gonna use this unit as a backup.
