Assembly

Placing all the main components on the tray is an easy task. As you can see, even the large Noctua tower cooler fits well and does not collide with any structural components of the case. The CPU power cable extension is a truly welcome addition, as it makes connecting this lead to the PSU very easy as well. Upon reinserting the tray, it becomes apparent, how much space you have within the ATCS 840. Every card, even the longest ones from either the red or green camp should fit easily.


Taking a quick look at the cabling within the case, I am happy to report, that there is nothing out of the ordinary, so you should have no problems connecting everything to modern motherboards out there.


Hard drive installation is a breeze as well. Just pull out the tray, squeeze the drive into it, slide it back in and push the lever close until it snaps into place. There are no screws required and the trays are made of a soft plastic, which does not bend out of shape over time.


There is nothing out of the ordinary about the optical drive installation either. After removing the front cover, simply slide the drive into place and push down the lock button on the side of the bay. That does hold the drive with an adequate force, but you may still want to use a single screw on the opposite side to make sure the ODD does not become the source of irritating vibration when used.


Finally, installing the PSU proves to be a simple matter as well. Just put it in place and secure it with the supplied screws and connect it to the required parts of the computer.


After all the major components are installed, you may place the black cover on the rear of the case. You better make sure, that you have connected everything before doing so, as you will have to remove four screws to gain access to these connections in the future. You can clearly see the 120 mm hole for the exaust fan, which was sadly not included. I really do not see a good reason for such a contraption.


Once everything was installed, I took some time to route cables nicely along the appropriate edges, trying to make good use of the openings in the mainboard tray. As you can see my results are fairly respectable, even though I did not spend a lot of time doing so. Turning the case around, you can see where most of my cables ended up running to their destination. The ATCS 840 has the potential for a very clean built - if you are willing to invest the time needed.

Finished Looks

After replacing both side panels, this is what the chassis looks like when turned on. There are no LED equipped fans, which is another small hint, that this chassis is not necessarily aimed at gamers. The optical drive fits perfectly in black, while I doubt silver or beige would look good in the ATCS 840. As you can see the black box in the back, blocks the PSU a bit, making it harder to connect a cable to it or flipping the switch.


The only LEDs that light up are the two on top of the chassis, with the power light being blue. Overall a very nice and actually quiet fan - if you leave them at the low setting. Pushing them to their limit does raise the air flow considerably, but also increases the noise level by noticeable amounts.
