It's been a few years since we published an enthusiastic review of Asrock's pricey yet powerful Vision 3D HTPC. The company has since kept our attention with annual updates, now on its fourth generation, the Vision HT 420D has received a proper upgrade to Intel's Haswell architecture as well as other improvements that contribute to the system's respectable list of features, making it one of the most impressive HTPCs to date.
Although the Vision HT 420D has largely picked up where the Ivy Bridge-based Vision HT 300 left off, the newest range isn't quite as diverse . The HT 300 series included models with Core i3 and i5 processors, while some were complete builds and others were barebones options that let you customize your memory and storage. For now, Asrock's latest Vision offerings are limited to two models: the 400D and the 420D.
