I’d be particularly interested in something along these lines in a 1U form factor if anybody is familiar with such a thing. Obviously the actual fan-less-ness is less important in that use case but I have a hard time justifying high wattage hardware for my home server operation, and racking provides a lot of convenience.

Take a look at the Supermicro brochure. Not sure the height is 1U, but the E100 and E302 series look interesting and are fanless. The E300 series I believe is a compact 1U but does have some active cooling. I myself have been eyeing getting one of these but haven’t decided on which one yet.

If you get a 1U mini-itx case, you can put pretty much whatever in there. Finding a heatsink that fits will be a challenge, but they're out there. Expect thermal throttling (or set a low power throttle, which is inline with your desire to reduce watts anyway)
