The packaging is a jewelry box style box with a thin wrapper hold it together. A picture of the unit, as well as a butterfly is on the front. Apparently butterflies mean “quiet” now.
The rear shows the aforementioned features and specifications, as well as some corner shots of the unit and a graph of its efficiency.
Included in the packaging is the PSU, a CD with a manual, a power cable, a printed quick start, a warranty card, the modular cables, and two rubber vibration dampeners.
