(disclosure: I'm a bit of a Corsair fan)
Who isn't? Maybe a few hundred people that might have had a bad experience with them at some point in time? Corsair is an awesome company that makes great products, even their budget models are better than a lot of other companies stuff.
And on topic, the H100 should fit fine up top where the 200mm fan is, it's supposed to hold 2x120mm or 2x140mm or the 200mm fan.
