BIOS has been modified to MrChromebox. You can now freely install ChromeOS Flex, Ubuntu, Windows, etc. M.2 SSD is not included, please prepare your own. There is some damage to the bottom rubber feet, but it does not affect operation. This is a used item, so there may be minor scratches and signs of use. The included accessory is an AC adapter. *Please note that we do not offer price reductions. Thank you for viewing.
