When looking at the rear of the case at first glance it does not appear to be anything remarkable until you begin to look at it closer.  It has the standard seven slot opening for your various video or accessory cards a 120mm exhaust fan and a generic I/O shield cover and finally the opening for your power supply.  When you are ready to install your power supply you will find that you are unable to install the power supply by lifting it into place.  You will need to remove the four screws from the rear of the case to remove the power supply mounting bracket, then slide the power supply in to the case.

It is when you look really close at the back of the case that you notice the pair of levers and slides.  At the top of each of the case you will find a lever that is marked with arrows as "Lock" and "Unlock".  These levers are what holds the side-panels in place, they can not be slide rearward without first unlocking each of these levers.

At the bottom and approximately 3/4 of the way up the rear of the case you will find two slides, these slides hold the removable motherboard tray in place.  To remove the tray it is a simple matter of releasing both latches and then pulling the motherboard tray towards the rear of the case until it is completely removed.

In an effort to insure the best possible cooling for your system Cooler Master has added a screen that covers nearly half of cases foot print.  If you were in the modding mood you could very easily add a pair of 120mm fans to the bottom of the case as we have seen on a few other cases we have reviewed.  If you look closely at the area where the rubber feet are on the bottom of the case you can see four small holes.  These holes are provided so that you can attach the four supplied casters which will allow your case to become somewhat mobile.
