Cooler Master CM 690 III: Never Judge A Book by Its Cover

The Cooler Master CM 690 III mid-tower chassis is positioned as a successor to the popular CM 690 II series. We reviewed the older Cooler Master CM 690 II Plus and found it a decent mid-tower casing, with options to mount up to 10 cooling fans. Some may find that it's an overkill; while others may like the abundance of choices.

The CM 690 III sports a very similar look as the older CM 690 II and CM 690 chassis. However, we find the newer chassis' facade appears smoother as the mesh drive covers are pushed out, rather than set into the recess of the front cover.

Speaking of cooling fans, the model of the CM 690 III that we will be reviewing is the CMS-693-KKN1. This new successor supports 9 cooling fans, one less than the CM 690 II Plus. At the same time, the company claims that the new chassis sports an interior that has been completed redesigned. One of its unique selling points is the presence of a drive enclosure that has the flexibility to install 2.5- or 3.5-inch drives. Let us delve deeper to see if the claims of the company hold true.
