Cooler Master ATCS 840 Full Tower Classic Case Review

Installation
I found the installation to be fairly simple to accomplish, especially the removable motherboard tray. To remove the motherboard tray four screws, not thumbscrews, need to be removed at the rear of the case. It’s pretty easy to tell the border for the tray to determine which screws need to be removed. Once they are removed you’ll want the handle straight out from the case to remove it. If you aren’t perfectly level it might take a little bit of wiggling to remove the tray.

Trying to figure out which motherboard standoffs you need to use is pretty simple with the removable lettered chart taped to the motherboard. I’d suggest removing this before installing because it could very well melt or catch on fire; it appears to be paper, but it has a thick plastic finish to it. Once you install the standoffs, remove the paper and attach the motherboard you’re almost ready to put the tray back in the case.

Now is probably a good time to hook up any expansion cards to your motherboard. Unfortunately there’s no screwless device for the expansion slots. The only downside I can see, other than not having a screwless design, to the expansion slots is that they are pointing outwards from the case, rather than mounted inside the case. Perhaps this is to give more room inside the case, I can’t be completely sure, but I have read reviews on people having difficulties installing larger cards because of the case getting in the way with the expansion slots sticking out of the case.

Now is a good time to install the power supply, top, bottom or both, because you have a little more room with the motherboard tray removed. Once that is completed you can slide the tray back into position and fasten the four screws.

I mentioned before that I would discuss the HDD racks and so now is the time. To remove the cage from the case just simply push the lever to the right, pull towards you and slide the cage out. The cage is composed of a very flexible plastic which makes this an interesting installation. You basically have to slide the hard drive on one side of the tray and then stretch the other side of the cage over the drive. While the first try may be confusing on trying to install I’m sure it won’t be complicated after your first take on it.

While no screws are needed to fasten the hard drives, two screws can be used for preventative measures.
