You broke down the differences between them pretty good.
All three cases have excellent standard cooling & options for improved cooling. All have the room for massive HSFs and the largest GPUs.
I'm liking what I read in the reviews on the K62 Dragonlord case though. I'd choose K-62 first followed by CM RC-690 II Advanced and HAF 22.
No matter which you'll choose I think you'll be happy.
