Thought its Aluminium body and its glossy looks, the ATCS 840 is the old for the new case for most mainstream modders. Going the design default of the HAF series gaming case, with the same construction and make-up, it definitely shows on the track of their OEM cases that you would have the same quality and build from every CoolerMaster case in stock; which is a shame after all that you have a tingling down your spine that there is something oddly familiar with the rest of the cases.
But anyways, the ATCS 840 is a same design as the HAF series without the open sided windowed case and a large bump in from the top of the case. This case has a normal three phase cooling system the cool air comes in the front and can be exhaust in the bottom, back and the top of the case and each cools a certain devise, the top for exhausting the CPU heat and the back and the bottom are the graphics and other peripherals. To add things up, it has a removal motherboard tray, for those easy to use hardware configurations without the usual complex surgery. It has a complete set of 5.2in and 3.5in drive bays with push button mechanism to remove or hot swap HDD’s, however optical drives, makes it easier to install but never easy way to swap. The exterior however is a smooth aluminium layer, but prone to usual smudging and intentional stocking in the side of the case, with no bundle of cleaning materials, we pushed on the build of the case. It has a push up front panel that hides well in the top of the case. And a grill that conceals two of the massive 230mm exhausts fans.
To much of the features the PSU and water-cooling package can be placed in either top of the bottom of the case, or just add another PSU for those hungry graphics cards at the bottom and the top one powers up the CPU and the motherboard. For the cooling potential of the case is great, with the same performance as the HAF, you would expect to have the same strong airflow; ready to cool pretty much everything hot and large, say a 4870X2 with a DFI lanparty X38, with a Intel core extreme QX6850, with a load temp of about 49 degrees average and 30 in idle average temp.
For much of the cases, this is a good alternative to the HAF series case, with the purpose of the ATCS 840 is to industrialise the HAF, for a more simple mainstream case out of the gaming market. The ATCS 840 is a mainstream alternative to the HAF series with good reasons.
