Homemade tin foil shroud with 2 x 250 CFM extractors from Home Depot (piped out a basement side window). Just enough to extract heat from 2 x S7s and 2 x Neptune cubes exhausting upwards.
Inserting setup don't know that I have seen to close to this before on neptunes. Do you have more pictures of the foil shroud? I would love to see a little more of it.
Thank you for sharing!
