Re: SBC?
the cooler they have for it is... massive. And tall. which means that a custom heatsink would have to be designed and fabricates for putting it in a multi-node server chassis, and TBH, there's already a fair number of those out in the wild already.
I think that this is designed more for the embedded markets or specialty systems where a decent amount of compute horsepower is needed, but it's not the star of the show.
