New to this and currently looking to buy a new laptop (specifically Lenovo T470/s or X1 Carbon or Dell XPS 15). What attracts me to the XPS 15 is the dedicated nvidia 1050. However, if I can figure out an eGPU solution I wouldn't bother with a dGPU and just buy the T470/s or X1 Carbon which both have a Thunderbolt 3 port.

My question is this. Since I already have a GPU (Radeon HD7950) and a power supply from my current desktop computer, can I just buy some sort of adapter and not bother with a $300+ enclosure? It would be sitting on my desk and I don't need it to be in a pretty box.

Thanks.
