Some high-end Mid towers and almost all full tower cases will support it. You need a tower with at least two 140mm fan supports on the top of the case for the radiator to fit.
I know off-hand the Corsair Obsidian 750D does, and I think the CM Storm Stryker/Trooper does as well, but not 100% sure on that.

This thread hasn't been updated in awhile (September 2013) but it also lists a lot of good suggestions for cases to look at. I would take a good look at the H100i list as well. It's a slightly smaller radiator, but most of those cases you could most likely get the H110 to fit, just make sure to look at the top for two 140mm mounts if possible.
Easiest thing to do is find a case you like and try to find out if someone else has attempted it.
