I use one of those (an older A10 with the E-350) for HTPC purposes and it works like a champ. For gaming it comes short for anything in the last five years, but for general computing it works just fine.
I have one of their Atom based units. It's been running almost nonstop for about 2 years, working as a hub for external RAID boxes, media server and the like. Never had a problem with it. I would recommend one to anyone for a small office computer, something to watch HD videos (it plays 1080p MKV's on a 1080p monitor with no problem at all) and surf the net on.
