The chaps from TweakTown spotted the Cooler Master HAF XM at CES 2012, this is a new mid-tower version of the HAF X. More details and photos can be found over here.
The HAF XM will ship with a trio of 200mm fans, one in the front and two in the top. The top two can be removed to allow for a slim triple 120mm radiator, but does offer more room in the top cover for those who don't mind a little modding for the fittings to pass through the top of this chassis if a thicker radiator is a must. You also will find removable hard drive bays which can hold an addition six storage drives, and the back, under the 120mm exhaust fan, offers eight expansion slots for those Quad-Fire or Quad-SLI users.
