Hardware pictures
(Pictures are coming when Wordpress allows, but its pretty much what you are imagining)
Installation steps
Using current firmware for Oct. 2018, plug in, automated update drivers.
Benchmarks
All benchmarks are on the internal display. I see a performance increase with an external monitor, but it seems more consistent to run them on internal hardware.

Comments
The Razer enclosure can power both the card (>180W) and the laptop (<65W), and it has a USB hub and wired NIC attached. For benchmarking I left USB and ethernet disconnected. I use a 2m Caldigit TB3 cable to connect the enclosure at my desk. Benchmarks are with Razer's 0.5m cable, but I haven't noticed any performance impact with the longer cable.

As you can see at my analysis https://egpu.io/forums/gpu-monitor-peripherals/tb3-cables-50cm-80cm-both-passive-and-150cm-active-tb2-cables-with-tb2-tb3-adapter-some-benchmarks there shouldn't be any big performance impact. The only notable impact with the active Tb3 cables it the fact, that they support only USB2.0 if used as USB-C cable.

Can i have a question?
What exact Latitude 7390 model are you using? I have a 7390 too, but i think my notebook dont support thunderbolt.
My model is the 7390 (not 2 in 1). It has one USB-C connector on the left side.
Can you post a picture about your windows device manager/thunderbolt connector (maybe with hardware id?)
I would like to buy an e-gpu, but dont want to waste money, if my notebook not capable to use it.
Thanks for the help!

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
