Seems they might be selling a combo of dual RTX Pro 6000 workstation cards (non-refundable), but the setup they have, unless they change how the GPUs cooling work, isn't gonna work out thermally if you stack two of those workstation cards on top of each other. But it doesn't say WS or "Workstation", so I suppose could be the server variant too? But also doesn't say...

Hope they have good overall cooling the case, cooling doesn't seem to be mentioned, it'll be a noisy little machine no doubt :)

They're [Max-Q] blower cards and there's a big gap between them so the cooling looks fine.

Page mentions liquid cooling, for what it's worth.
