If it's Maxwell I don't think everyone has them in production just yet.
I keep mine on a piece of wood because of my thick carpet but this new case has a side mounted fan so it's no longer an issue but I still prefer it. Space above or below it? The Geminii M4 is a pretty good low profile cooler if you need more space. I had great results with it!
Less is more I love the H440 because of that! I showed it to my IRL BFF and she made me use it on her build and it also looks like the black version will go in my lil brothers.
I just got my 120g SSD now I have to figure out how to clone the smaller 64g SSD so I don't have to reinstall everything.
