The first thing that caught my eye here was the rear 80mm fan; particularly the fan grill, or better yet, lack thereof. I am a big fan of free-flowing air (no Pun intended), and CoolerMaster's choice to not include a rear fan grill on the frame of the case was definitely a good one. Instead, the case fan grill is a simple wire grill, which can be removed should you be inclined to do so. Also, notice that the power supply bracket is removable. This bracket attaches directly to your power supply, which is then slid into the case from the backside and fits nicely into its own "holding station". More on this later. The final thing that stands out with the rear of the case are the thumb screws used to hold the case panels on. These screws are also used to secure the removable motherboard tray.
