Hello guys. I am watching this thread for about some months because i have also a lenovo y510p and i was interesting for a solution for external gpu because now the laptop is kinda limited in power on gpu. I would like to ask if it's possible to use a cable like this https://www.aliexpress.com/item/Riser-Gen3-0-PCI-E-PCIe-x8-to-PCIe-x16-Graphics-card-extension-Riser-Ribbon-Cable/32839943463.html with the end of the connector being in sr mode as the pictures show into the link to extend the internal of the connector combining with an hdd caddy like this https://www.amazon.com/Nimitz-Drive-Caddy-Lenovo-Ideapad/dp/B00NAMUETC. At the end of the hdd caddy with some modification we can put the end of the riser connector and then with another riser like this https://www.aliexpress.com/item/Riser-Gen3-0-PCI-E-3-0-16x-male-To-pcie-x16-female-Right-Left-Elbow/32832150338.html?scm=1007.13339.90158.0&scm_id=1007.13339.90158.0&scm-url=1007.13339.90158.0&pvid=f0e9c06e-bae3-4a72-8af1-63cd1f8c80fa&_t=pvid:f0e9c06e-bae3-4a72-8af1-63cd1f8c80fa,scm-url:1007.13339.90158.0 we can easily connect and disconnect the gpu and retain portability for the machine. The only thing i can't understand is if the ultrabay port is something like PCI-E PCIe x8 connector or something else because i don't have a pci-e x8 connector to compare with ultrabay connector. Something like that linus tech tips did in their video.
