I know that the discontinued Lian-Li Q33 and Lian-Li Q34 are both compatible with Noctua D15 (personally I use Q34 + D15). Though for the new one you linked I'm not sure.
You cannot find the spec because that cooler is still a prototype. Steve did mention in the video that the prototype is 165mm tall and the other dimensions are similar to the NH-D15. 165mm CPU clearance is a tough spec to fill for any small case.
