This is great work! I have a few questions though. How much strain does this place on the actual thunderbolt port? Isn't there a lot of heat generated in the process? I am also pretty confused with the wiring of the whole set up. I am definitely intrigued into trying this set up, but on the contrary thinking about buying a new tower PC, (but that would be a bit more expensive). Could you please explains the first two steps more deeply? Or would it become obvious once I actually buy the Sonnet Echo SE? Thanks!
