I can’t speak to the steps outlined in the post, as much of that is also beyond anything I’ve done, but the kit pictured is a Fermzilla pressure fermenter with what looks like a hop bong upgrade attached to the top, though the hop bong looks closer to the one in the description video thumbnail than the picture in the product listing.

Not affiliated with the company or the products, just where i found the gear after a quick look around:
