Over the last couple of years, mini-PCs in the ultra-compact form factor (UCFF) have emerged as one of the bright spots in the troubled PC market. Zotac is no stranger to this segment. In fact, their nano xs units came to the market before the Intel NUC, even though the NUC is credited with kickstarting the UCFF trend. Intels Bay Trail family of SoCs has proved to be an affordable and low-power candidate for UCFF PC units. We have already evaluated a couple - an actively cooled GIGABYTE BXBT-1900 and and the fanless ECS LIVA. This review provides some insights into what the passively cooled Zotac ZBOX CI320 nano brings to the market.
