I'm stuck between the Fractal Design Define xl and the Corsair Obsidion 800D. I like black plain cases, so these 2 are pretty much it. I checked out the Switch 810, but it didn't look sturdy enough, which could be because I spent a lot of time looking at the define xl. My biggest hangup about the fractal is that it doesn't have room to fit in a Corsair h100. The best it can do is an h80. Has anyone had experience with both cases? It seems like a $100 price difference is quite a bit for want of a h100, so I'm trying to find out if the 800D is worth the extra.
