there was also the Mozart TX by Thermaltake. interesting how Tt has made a lot of dual chassis, eh? LoL!
That is the one I found/posted. Isn't it? Maybe a didn't check the link, but it should be the TX variant.
When i first read you post I was pretty sure I knew exactly which one you were talking about. I had reached out to a friend because he had one and all i remembered was a weirdly tall rectangle with an iTX chamber, and it was the Mozart he had. He was fiddling with peltiers and I'm pretty sure he put the controllers and such in the iTX chamber. You were faster googling than me reaching out to him though.
No worries, the effort is appreciated nonetheless. What really threw me off was I had thought it was much smaller than it actually was. The TX is damn huge! It's no wonder I went the modding route instead of getting that case or one like it.
