Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    Bought this to replace a previous version of this model that finally failed after just over 10 years of hard use, which just happens to be the length of the warranty. I expect a similarly long lifespan out of this product. Connectivity is simple to use, but I was caught off guard at first by how it operates upon bootup or waking from sleep, since it runs the fan at full speed for a few seconds upon powering up (this is by design). Otherwise, it's relatively quiet.
