The Cooler Master Cosmos II is the biggest normal case is I've seen myself.
It's size looked like an old SGI machine or it at least looked to me like the perfect case for a hardcore graphics workstation.
Dimension wise you are correct, I also have not seen one larger. Case Labs doesn't make anything bigger, and the 900D isn't bigger. That Xigamax thing isn't as big. I currently use a Cosmos II and while I like it, the interior configuration wastes a lot of the space. I want something that resembles a good ol'fashioned "what we're used to" computer case, but makes you go WTF?!@?
@@@!@!!!!! Like an old school 1960's style giant console TV. I thought about one of those desk things, but they don't work. I think what I'll do is actually BUY an old school console TV and just retro the entire interior, Frankencase a bunch of old cases I have together to create a massive interior space. Yea...
