EDIT: The mistake was mine! This does support surround via HDMI, it was a switch I was using that caused the problem! I hooked it directly to the sound bar and it worked like a charm! Upped my star rating to 5 stars. Granted, I've only had it for a few days, but it's working well and is just what it claimed to be.Very fast boot up, Windows set up was a breeze, and it's quite fast for a lower-priced machine. This machine will likely be fine for folks who would like to do basic computing/web browsing, playing games (though likely not high-intensity games, this is hardly a gaming PC) and watching movies via HDMI to a projector.
