media PCs as of late, and they all come in different shapes, sizes, colors, and prices. The latest VidaBox model, dubbed the ZERO, is the most recent model to also takes noise output into account as well (yes, we've eyed many more previously) -- the company even goes so far as to promise that the ZERO will be "100 percent" silent. VidaBox's $4,400 machine is packed with an AMD X2 dual-core CPU, up to 1.5TB of storage, dual standard def tuners, optional dual HDTV tuners, an HDCP-compliant NVIDIA Geforce 7950GX2 graphics card, and most enticingly, optional Blu-ray or HD DVD drives. In addition, all ZERO systems -- along with future VidaBox high-def CableCARD systems -- will be upgradeable to CableCARD compatibility in 2007, which is when Vista is supposed to be released (cross your fingers). Although the model pictured above comes in black, VidaBox says that other color options, including silver and "combination" are also available -- perfect for the few but proud Oakland Raiders fans out there.
