Is Spec Alpha completely compatible with H100i v2?

I was looking forward to buy this case but on several reviews I found online stated that only the front part can take the radiator but you'll have to remove the drive cage or do a push-pull config

But I saw this build - [ame]

Now I'm completely confused what's going on and whether it can be installed without removing the drive cages
