Need a pro's opinion on making my water cooled eGPU!

I plan on making a water cooled eGPU case with a Sonnet eGFX Breakaway Box 350 and a used EVGA GTX 1080 FTW Edition with a water block already on it. My problem occurs with the actual method of water cooling the card. From the look of the Breakaway 350, there seems to be 2 spots on the top that can fit some 120mm components. I went on EKWB's website and found a 120mm bracket to hold a reservoir/pump and I was thinking I could put a radiator on the side of the eGPU case, the bracket on the top (with the reservoir/pump) and have soft tubing go from the pump to the radiator, then to the GPU, then back to the pump (I'm actually not sure if that's how it works so correct me if I'm wrong please). My problem comes with what tubing and fittings to get as well as if my idea would actually work. I'm not that experienced with water cooling or handling hardware, but I've watched hours and hours of YouTube videos if that gives me some kind of credibility (it probably doesn't).  ALSO, is it bad to leave an eGPU's case off and have the chassis and internals exposed or does it not matter because this idea obviously uses space outside the Breakaway Box's covering.

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