FSP CMT340 Case Review

Back at CES 2019, we got our first look at a few new cases from FSP. While typically known for their power supplies, FSP is also in the case designing business, and we have been given the opportunity to take a look at their latest mid-tower gaming case, the CMT340. Claimed to be the world’s smallest mid-tower chassis that can support a 360mm radiator, the CMT340 is decked out with two tempered glass panels, and includes four addressable RGB fans as well. Let’s not waste any more time, and get this review under way!

Special thanks to FSP for supplying the CMT340 review sample!

The CMT340 comes to us in a standard cardboard box that shows off the case’s looks on the front side, along with some pretty cool artwork as well. The back side of the box gives an exploded look at the case, and a bit more of information about the CMT340 and some of its features.

Once opened up, we can see that the CMT340 is initially protected by a plastic bag, keeping the surfaces of the case free from any cosmetic damages. Keeping the case secure in the box are two form-fitting foam end pieces, which is the norm for 99% of the cases we work with.



The FSP CMT340 comes with a very modest accessories package, composed of the very basics. In addition to a fold-out installation guide, we have a small packet of various screws for component installations, and a handful of zip ties to help tidy up cabling. The last component of the accessory pack is a power supply mounting bracket which is required for installation, due to the small nature of this case. We will cover this need later on in our installation section.
