An External GPU for an old Laptop?

[Laptop External Independent Video Card Graphics Dock Mini PCI-E Version for V8.0 EXP GDC Beast]

[Old NVidia 680]

[650W Power Supply]

[Razer Tomahawk Mini ITX]

Testing with old [Toshiba Satellite S55t C5222 HD]  laptop…

There should be a PCI-Express connector under the WIFI adapter.
