The Coolermaster ATCS 840 utilises an all aluminium construction and weighs in at 13.25kg, not the heaviest case we’ve seen at our offices but not light by any means. Also, at (w)243 x (h)580 x (d)630 mm it is huge and has a wide stance which compliments its towering height. Our sample was supplied in black, a colour always flattering to the beautiful brushed aluminium finish. Unlike some of the other full towers we’ve looked at recently, Coolermaster have chosen to include some stylish curved edges, specifically on the sides of the front fascia. There are no windows or fancy vents to speak of, just a clean well designed case.
Looking at the front of the unit we can see the front panels for the six 5.25” bays, with one of them including an adaptor to fit a smaller, 3.5” device. Below those bays sits the 230mm 1,700 RPM intake fan. Coolermaster have placed a panel over the intake which is slightly lifted from the surface and leaves the case looking sharp without compromising the thermal dynamics. The 230mm fan is protected by a dust filter which is fully removable, a great addition by Coolermaster and will certainly aid with cooling and maintenance over time.
Moving up to the top of the case, we can see that Coolermaster have placed all the front panel ports in a pop up flap, and have provided a healthy range of connectivity. The panel boasts eSATA, a Firewire port, 4 USB ports, and audio jacks. Just in front of the panel lies the power and reset switches along with the LEDs. We’ve seen this sort of placement and configuration quite a few times recently from various manufacturers and it appears to be the way to go at the moment for full tower cases.
The back of the case is fairly interesting and part of the panel where the water cooling holes are located is able to be removed to provide support for a top mounted PSU, should you wish to mount one there. The ‘default’ location for the PSU is at the bottom of the case, where the frame is already open for a PSU. Looking at the centre of the rear panel we can see that Coolermaster have vented the 7 expansion slot covers to aid with thermal performance, especially around the graphics cards, a technique which is growing ever more popular among chassis manufacturers.
At the bottom of the case they have attached four feet to support the case which are almost identical to the ‘home theatre’ style feet we saw on the Silverstone TJ10 case recently.
