I viewed the LTT video and saw the PCIe slot was a x4 slot but closed.
You can modify the slot by cutting the end to open the slot, but that comes with some risk.
If the slot was open natively, it would allow larger AIC or GPUs to run and incease compatiability with PCIe.
It’s a suggestion/request for the PCIe slot to be open ended. I dont know if it can be done before first shipment.
Keep up the great work Framework Team.
