Got all the DIY footprints right, gg ez :)

Those right-angle SMD .1" pin headers are a bit expensive, as are the 8 LTC6090. But if this attempt works, it'll be a great foundation for further optimization.

Someone in the Discord chat thinks, that those MOSFETs will not be able to sink 375W through the thermal vias. Not sure if I agree, will have to test ... what's your guesstimate?

And no ENIG either, it was completely wasted in the early stages of development ... will do that when it's final and RTM :)

375W will cook the mosfets for sure. You have Rthjc=0.4K/W, this amount of vias should add another 1K/W or so, then you have TIM (HAL has very poor planarity so you'll need a thick layer). I would operate them at <50W dissipation TBH, that is if I were to use good active cooling.
