You might want to look at Terramaster NASes. E.g. their F4-423 is basically an Intel NUC married to a SATA controller. They have an internal USB port where you can pull the OEM flash drive and insert your own, then install e.g. UnRAID or OpenMediaVault on it.
That will be my next device if my Synology DS415+ finally dies.
