The whole cbo vs cbox thing is a bit unfortunate, I know Intel tends to
forget to type the last letter, but could we be consistent?

Ideally Intel would have called the thing a Cache Coherence Unit or
somesuch to match the Power Control Unit, But seeing its called C-Box, I
don't see the point of saving the 1 character and obfuscate the name.
I've even seen CBO Box used, which is of course completely ridiculous.
