Found it, was a promo on the HyperX channel .
I'm not sure if it was on the main LTT channel or not, but it was a video that had custom built case made from one piece of aluminum, bent into shape to make a nice case. The two key points I remember was the case didn't have any switches on front and Linus said the person who used the case had to use the power switch on the motherboard and the front of the case was all fan mounting. I can't find the video again and I am losing my mind, I've watched 3 hours of videos and can't seem to find it. it is not a video about an INWiN case.
