Tech Power Up have reviewed the Cooler Master HAF Stacker - here's an excerpt from their conclusion: [QUOTE]"The Cooler Master HAF Stacker is by no means reinventing the wheel as other case brands have been offering enclosures with the ability to hold two separate systems. But Cooler Master has managed to refine the concept behind doing so well by taking it from being a niche product and making it something with mainstream appeal. The fact that you are able to easily detach the two compartments to rearrange things within the case add to their refinement. Yet Cooler Master was not as thorough as I would like as there is no possibility to turn the second system inside the smaller chassis on without going out and buying an accessory, for example. The entire chassis, top and bottom, also only ships with two basic fans. In a perfect world, the larger chassis should have shipped with two more cooling units in the front. Next, the smaller unit in the set should have been a fully configured 915R since Cooler Master refers to it as such in their specifications table. Those last two points keep this case from moving past our Recommended award."[/QUOTE] [CENTER][IMG]http://tpucdn.com/reviews/CoolerMaster/HAF_Stacker/images/hafstacker.jpg[/IMG][/CENTER] Read their full review [URL="http://www.techpowerup.com/reviews/CoolerMaster/HAF_Stacker/"]here[/URL].
