Outside/Inside/CoolingBefore we present you with the performance results of this case, we have to install our test system in it, of course! The side panel can easily be removed as Coolermaster uses
thumbscrews to fasten both side panels, the removable motherboard tray and PCI cards.
The outside of the case features excellent finishing; no sharp edges could be detected, this makes handling the case a hazardless experience.

The inside however is not that child proof; sharper edges are present along the 5¼ and 3½ drive bays. But without any quick uncontrolled movements you will not wind up with cuts.
The Praetorian 731 comes with 4x80mm fans installed by default, 2 in the back and 2 in the front providing excellent airflow; dust filters are present on the front in-takes.

At the top is an I/O panel with connections for USB, microphone, headphone and fire wire.

Coolermaster provided a blue led fan for replacing the I/O unit for those who want the best thermal performance. This fan comes with a good looking grill which integrates nicely into the case.
