OCC has published a new review on the Coolermaster ATCS840 Case

Keeping this case clean and up to date is made easy, thanks to the removable motherboard tray. Installing hardware was a breeze, nearly everything can be done outside the case, leaving you ample space to work. The processor's heatsink backplate can even be changed just by taking off a side panel. Speaking of heatsinks, the case can accommodate up to 200mm high coolers, so even the tallest ones out there will fit without a hitch. The whole enclosure is also a breeze to take apart, especially after a quick glance over the well detailed manual, making maintenance that much more enjoyable. Fortunately, there is an air filter in front of each intake in order to keep dust outside as much as possible.
