Among all the Predators, Acer ammounced a redesigned Aspire all-in-one with the Predator-like V-shaped base. In fact, the U27 looks very much like just a monitor; it's extremely thin, with barely a bulge to indicate there are components inside.
The key to its slim design is the incorporation of its LiquidLoop fanless cooling system. The rest is pretty standard. The system has a built-in subwoofer with Dolby Audio Premium, but I wasn't terribly impressed -- there are no front-driving speakers, so the sound is oddly muffled. And the 1,920x1,080 touch display isn't very good because of the relatively low pixel density (about 82 pixels per inch); you can see the individual pixels from normal sitting distance and it's quite distracting.
Still, it has a relatively low price given the rest are all current components -- it starts at $1,100 -- and there's a less-powerful 24-inch model, the Z24, that starts as low as $900. They'll both be available in July.
