Finished Looks
The DeepCool AK620 Digital won't grab your attention with excessive ARGB lighting or other flashy features, at least with everything turned off. Instead, you get a clean dual-tower design that is aesthetically pleasing due to its understated elements. When the ARGB lighting is enabled, it becomes an accent to the display rather than an overwhelming light fest. Sometimes, less is more, as seen below.
Concerning memory and graphics card clearance, you will be limited on RAM height to a certain degree. Ultra-tall heatsinks won't fit without things looking a bit absurd. However, if paired with standard height or slightly taller heatsinks, everything will be fine. On the GPU side of things, there were no issues to speak of.
Concerning ARGB lighting, the DeepCool AK620 Digital takes a more subdued approach compared to the usually excessive levels on most products in today's market. The lighting elegantly frames the display, helping it stand out just enough to work together beautifully. Meanwhile, the temperature and CPU usage aspects of the display, while simple, are the most likely use case for most consumers, offering a quick look at what is going on without enabling an overlay in-game with 50 different things being reported simultaneously.
