lf your HTPC uses 200-300 Watts you are doing something really wrong. So basically... it's a TV. Kudos on the 3 Watts though. Basically the same power consumption as my Pentium Mobile based HTPC. And unlike the HD HDR-350Q media center that doesn't need a separate tuner box (add another 10 Watts) so you can record a different channel from the one you are watching on the TV.
