Wanted: HP protective racks for modern, high-end acoustically and thermally challenged workstations

[joselso]

In several HP publications, three types of sliding rails rack-mount kits are described, intended for four generations of high-end HP Z-series workstations:

- Kit NN124AA , in 'Sliding rack-mount kit installation' (2009) for HP Z600 and HP Z800:

- Kit B8S55AA , in 'Rack Mounting and the HP Workstation' (2012) for HP Z6/Z8 (shown with Z820😞

- Same Kit B8S55AA , in 'Rack Mounting and the HP Workstation' (2016) for HP Z6/Z8 (shown with Z840😞

- Kit 2FZ77AA , in Z-Technical White Paper 'Rack Mounting and the HP Workstation' (2019) for HP Z640/Z840/Z8 G4 (shown with Z8 G4😞

Now, in all these publications it is stated that for installing those sliding rack-mount kits in earlier HP legacy racks, models E3660B, E3661B, E3662B, E7590A, J1450B or J1487A/B, an extra legacy-rack adapter-kit WD587AA is required.

It turns out that those models legacy racks are no longer manufactured by HP, but they are now available from Keysight who inherited them from Agilent after HP separated its computer business from its measurement instrument business, many years ago.

Nowhere have I found reference to, or part-numbers of, modern HP racks, for which the rack-mount sliding rails kits are intended for direct installation (without the extra adapter).

So, my question is: What are the models/part-numbers of modern, currently available HP racks intended for modern generations of high-end HP Z6/8 series workstations?

I expect such racks to feature protection from acoustic noise, combined with efficient cooling, since the workstations are operated in populated offices, unlike server-racks that have to be confined to separate rooms and are remotely operated.

I tried... you found all I did too.  This one was the best:
