The HDMI output and low power, low noise nature of the AspireRevo makes it an affordable HTPC consideration for those looking for a quick drop-in solution. One potential worry point is that our reference Ion from Nvidia had an optical audio out, but we can't seem to spot one on the AspireRevo. As far as we know, the GeForce 9400M can't pass audio out through HDMI. With dimensions measuring 7.1-inches square and 1.2-inches thick, it’s sleek enough.
