So I was planning on buying a Razer blade stealth and wanted to get the Razer Core to go along with it for some gaming, but the $500 price tag is way too much. I was wondering if there was any way I could make a similar enclosure to the razer core out of a smaller PC case that could connect through the laptop's thunderbolt 3 port(which would cost much less). If it can be done, do you know what specific parts I would need besides the GPU and power supply?
