Cooler Master introduced the new HAF XM on April 24. The company's HAF series is instantly recognizable, although the XM moniker is new. M stands for mid tower while the X means that HAF X was the role model for the new case.
A mere glance confirms it’s a case from the HAF family, notable for excellent cooling. It would be safe to say that HAF XM looks somewhat mellower than HAF X, which is more like an armored vehicle of some kind.
