Case for $1850 Build

In the $1850 video Logan used the Phantom 820 case. I like this case but it is a bit large. I really like the CM Storm Scout II, because I move my case alot. The build features a ATX board, which will fit in the Scout and the NZXT Kraken x60, but since it is smaller than the Phantom it may hinder some airflow(please enlighten me if it does). If you have a recommendation on a different case or if you have an opinion on which i should choose of the two cases mentioned plelaese tell me

you could get an m atx board and get the fractal design define mini its a pretty cool case the define r4 will fit a full atx though and can have a window 

I love the Phantom 820 (I got one but I havent put my build together yet). But I also love the CM Storm Trooper, which you should check out!
