Not really all too modular, seems kinda like one of those proprietary types. All the "value-add" garbage on the TB, "no wires thru the firewall because we even put the ecu on the TB too (so it can cook quicker)" just screams RUN AWAY.
If they did it right, the air being drawn though the throttle body would keep it quite cool, add gasoline that likes to draw heat and it will stay even cooler. Add your engine fan and I think things will be just fine. Now shut off with the hood closed would be a different story as your bay becomes a good oven, but it's only like maybe 150 degrees? Seem even 60's electronics can survive that.
In the end if you grew up with carbs, why change what your used to. If you grew up with computers and modern vehicles then EFI makes more sense to you. After doing a lot of fuel economy engineering, the biggest downside to carburetors I see is the changing of gasoline compositions to resists evaporation and additives that are all designed to be used with EFI because no OEM is using a carb. EFI will always win in the end and it's not by anyone's choice, the OEM's and fuel company's driven by government regulations drives this buss.
