"Our initial thoughts was that this case is designed for micro ATX motherboards. However, it isn't. It takes full size ATX motherboards... with ease. So how did Coolermaster manage to reduce the height of this case? Instead of mounting the power supply unit vertically above the
motherboard they mounted it horizontally. This produces two quite different results. The obvious one is that it reduces the height of the case. The other is that you have height restrictions on the heatsink/fan unit you are able to use."
