I'm a bit surprised that this kind of incredibly engineered hyperconverged rack system isn't doing some form of liquid cooling.

99% of data centers do not have liquid available to the rack. Liquid within the rack doesn't really help.

Not worth the capex to do that. Air cooling with evaporators up front is pretty standard and works great, not to mention fewer moving parts.
