The ATCS 840 is a rare product in the sense that we have really found nothing that we dislike or would change. This product has come together very nicely, and although it features nothing really new when compared to say the HAF 932 for example, it does feature all of Cooler Masters latest design innovations.
"Cooler Master is highly regarded among computer enthusiasts and gamers for building quality products and with the ATCS 840 this still holds true. The ATCS 840 is an extremely large case that can accommodate dual ATX power supplies, an EATX motherboard, six disk drives, and six external 5.25" drives. You could also run multiple GPUs in this system too quite well on top of that."
ATCS 840 extends this legacy with the addition of today's latest advancement in ergonomics and system cooling. With a timeless design and unmatched attention to detail, the ATCS 840 is set to stir interest once again.
The RC-840 is an extremely well-constructed enclosure with a solid chassis capable of sustaining the worst accidents without warping the chassis. While the panels are not 6mm alloy and seams were not welded, the ATCS survives the most harsh handling.
One particular area of interest that really impressed be was product functionality. I'm completely sold on the motherboard tray cut-out which allows me to remove the backplate of a CPU cooler without having the remove the entire system. Even without this feature, the sliding motherboard tray would make for a decent second-favorite. Using 230mm cooling fans in three different locations of the RC-840 is a guaranteed way of ensuring Advanced Thermal Cooling, but the negative inner-case pressure might add-up to be too much for some exhausting video cards (such as high-end NVIDIA and ATI products). Tool-less drive bay trays and clips make installation a snap, and the removable fan filters should keep the innards nice and shiny.
