Cooler Master ATCS 840 Classic Case - Black

ATCS 840 constitutes a classic all-aluminium design that builds on the legacy of the original ATCS design. The aluminium construction not only allows for a lighter weight but complements the thermal design seamlessly with three 230mm fans, dedicated air duct for graphics card cooling and HDD cooling module for superb cooling. Extra attention to make sure this elegantly design chassis is easy to install and maintain, which includes: slide-out motherboard tray along with easy CPU cooler-remove slot, tool-free HDD casing, patented finger pressing 5.25" drive to dust filter. Lastly, it gives users the freedom to choose any components they desire, as it supports the latest standards such as E-ATX and dual PSUs.

got this case today due to the fact that i have a corsair 700d as well i got this case the coolmaster for two good reasons one its excellent for air flow. some thing corsair needs to work on and two its a better looking case as the 700d looks dull. I give it to coolmaster as this case is light as well and well made nice one coolmaster.

This case is sublime. So much space you can fit anything you want in this case.

Removable Mobo tray makes for the simplest, stress-free build imaginable and cooling is fantastic.

Only slight gripes are:

1. May need to get some soundproofing to reduce slight thrum of PSU fan if you use this case on wooden floor - but always a good idea anyway;

2. Tool-less 5.25 installation easy, but feels a little insecure when using the open/close button on drives (a little movement of drive unit) but nothing to get upset about.

Would recommend to anyone wanting a big case that's easy to cool quietly and efficiently.

Build quality superb.

Classic Case

Just received this case for my new I7 build and it did not disappoint. Loads of space, removable motherboard tray, lots of stock fans and room for more optional if you want, and the duct thats attached to the graphics card slots was a nice touch. My only little gripe is that there was no side window but that was a simple fix as I made one myself. If your looking for a great case thats made for the future you can't go wrong with this.
