Pizza box and lunch box in SMBIOS: What are they?

Arpith asked:

The SMBIOS spec lists Pizza Box (05h) and Lunch Box (10h) as the meaning for System Enclosure or Chassis Types. The other stuff makes sense but these do not. Are there really chassis types that corresponds to these types? If so, could someone please point out examples for them.

My answer:


As several people noted, “Pizza Box” refers to a 1U server.

“Lunch Box” refers to a portable computer inside a transportable case vaguely resembling a child’s lunch box. This type of computer usually has a keyboard and display that pop out of the case somehow. These are typically used in military applications.
