The power!

One caveat of the NZXT H440 is there is no place to put an internal CD/DVD drive. I wasn't sure how I would install Windows w/o a dvd drive, but I ended up putting Windows on a USB stick and was shocked how much faster installation was. So it turned out to be a non-issue for me, and I suspect most gamers these days don't need a DVD drive, but it's something to consider. If you can get past that, it's really a fantastic case.

One thing to consider re: i5 vs i7... the CPU is actually becoming a factor with 4k video. If you don't plan on getting a Titan X or pushing 4k video, then don't worry about it. Otherwise, imho, it's worth spending the extra $100 or whatever to get an i7 to give yourself more options down the road.
