The headline is that its now packaged as a tightly integrated rack unit where Nvidia has complete control of everything, down to the cooling. Cooling has a significant problem with the rollout of the GB200 platform, where they relied on third party integrators to design and integrate cooling.

Nvidia have optimised the design to be 100% liquid cooled and designed racks that plug directly into Coolant Distribution Units (CDU's) operating at 5 bar pressure, which will be end of row or facility wide units. These will be 3 metric ton sealed units that no-one will touch until decommissioned.
