Obviously different marketing copy speaks to different people. But that is referring to how, when you buy a rack from us, you don't need to put everything together and cable it all up: you pull it out of the box, plug in networking and power, boot the thing up, and you're good to go. Installation time is hours, not days or weeks, which is the norm.

Hypothesis: "no cables" and "no assembly" here is analogous to the term "serverless". Or, more abstractly, the word "literally".

Yeah including networking and storage together with virtualization is what makes hyperconverged infrastructure hyperconverged. Otherwise it's usually just called converged infrastructure.

It's nice, it's just nothing new.

"Real" mainframes have RAS (Reliability, Availability, Servicing) features such as hotswapping for all hardware components and automated HA/workload migration across physical racks. They can also do SSI (single system image), i.e. run a single workload across physical nodes/racks as if it was just multiple 'cores' in a single shared-memory computer. Oxide computers will probably end up doing at least some of this (namely workload migration across racks for HA) but saying that it can comprehensively replace mainframe hardware as-is is a bit of a stretch. In terms of existing hardware it's closer to a midrange computer.
