The Phanteks Enthoo Primo has lots of vents. More unique features include mounting points for liquid cooling tanks, along with room for two power supplies.
We have to make a separate mention of how thorough the accessories are included with this chassis. Most of the time screws and installation tools come in little plastic bags, but Phanteks put everything in a very practical box with compartments. The manual is exemplary as well, printed on quality paper. You also get a separate fan holder, meant for extra cooling of your hard disks.
