Attention There is an onboard M.2 NVMe socket, but it has a crack. Its function was tested OK, but better not to put the system drive there. Its motherboard doesn't integrate a TPM module, so every time the machine is started, you need to press F1 to boot the system. I assume this only happens with Windows 11; if you downgrade it to Windows 10 or use Linux, there wouldn't be a problem.
