I want to know if the current cooler master case for the main board will be compatible with the swappable GPU from the 16 inch frame work laptop.
Welcome to the forum.
No. The current cooler master case is for the Framework-13 motherboard, not the Framework-16. The Framework-13 motherboard cannot connect to the Framework-16 GPU expansion module.
For the expansion bay GPU, as I recall, Framework previously mentioned that they would provide a way to adapt the expansion bay module as an eGPU. I would expect that it could then be connected over USB4/TBT4 to any device supporting PCIe tunneling over USB4/TBT4.
TL;DR, yes, at some point in the future, with the eGPU enclosure that Framework will make.
I hope there will be a cooler master case for the 16 motherboard. That is a nice appeal for upgrading down the road.
It’s just 3D printing or molding some plastic. I see no reason why such a case should not be available as soon as the first 16" MBs rotate out of laptops.
The eGPU enclosure was more a proof of concept. We don’t know if or when Framework will release a real one. If they do release one, then it would be compatible with the FW13 mainboard via USB-C. Wouldn’t matter if you were using the Cooler Master case or if it was still in the laptop chassis.
