The OMWAVE's EH1 media PC

Nah, it doesn't run on Microsoft's Media Center PC operating system (which may be a plus or a minus depending which way you swing these days), but OMWAVE's new EH1 Media PC does have that A/V component-look you'll want so it won't look all out of place in your living room. Comes in three versions (they get all cutesy and call them "XL", "L", and "M")
with up to a 3GHz processor, DVD burner, and up to 1GB of RAM, plus they also toss an RF remote and a wireless trackball keyboard in there for some proper couch surfing.
