There's lots of interesting things in dmidecode, including the asset tag of the machine. If anyone is interested, on both Lenovo and Super micro servers you can set the asset tag. Lenovos do it with Redfish, with Supermicros, you have to use their "sum" tool. Using it, you can also modify the model name and serial number of your Super micro motherboard. Which cam be useful when your idiot system integrator can't be assed to set them correctly themselves.
