The Nanoxia Deep Silence 4 does not, so to speak, reinvent the wheel. It sports a timeless, simple exterior design and functional interior. However, the Deep Silence 4 scores brownie points for its excellent feature set. You have both USB 2.0 and USB 3.0 connectors and two individual fan controllers. Each of these sliders can be hooked up to three 3-pin fans, allowing you to adjust the speed of up to 6 units. Considering the fact that the Deep Silence 4 can only hold three case fans, this extra will be useful to those who want to go all down and dirty by controlling CPU or water-cooling fans directly, but a single such controller would have been just fine for most of us. Nanoxia also includes a 5.25" to 3.5" adapter, which is something other companies tend to skimp on.

Looking at the interior, you have everything you would need: a modular hard-drive cage to metal trays and plenty of room to route cables. The optical drive-bay locks work well enough, but still allow for screws to be used, and you can install fairly large CPU coolers and graphics cards within the chassis. As you can see, there is nothing extraordinary within the case, but pretty much everything that is present works well, and you do not end up craving other features. The Deep Silence 4 is by all means a German chassis—no frills, but all business, and it does so very well.
