Yes I understand, but will your included service actually verify that everything is set up correctly, meets advertised parameters, and sign off on it? (Such that the customer can start using it immediately afterwards.)

Or does the customer need to take on some risk and hazard associated with installation, configuration, initial boot up, etc.?

e.g. If someone buys with the intention of using it up to X FLOPS, and the machine only delivers Y FLOPS once it's all said and done, what happens?
