About fitting the case... mine in fact did not. At least not some Cooler Master mid tower I've been using for years (not sure about the model).
I had read about the Gigabyte Gaming OC having this very large 3 fan cooler but I underestimated just how ridiculously large it really is.
It absolutely dwarfs both the 3080Ti and 2080Ti models I have, and this seems rather silly because 4070Ti cooling requirements just aren't all that great.
Oversized coolers seems to be a thing a lot of 4070Ti models have in common. Sadly, there is no snazzy Founders Edition available to show OEMs how it could be done.
So yeah, it turned out I could not install it in the PC I had in mind, and instead had to put it in another one that is in a CM Elite 500 case. And took its 3080Ti to put in this PC.
As both of these are almost identical 5900X systems, it works out. But I was certainly annoyed. And would caution others to check closely before buying.
