I decided to build a dedicated HTPC for $260 out the door. Bought a Dell Vostro 220s barebones and added memory, processor, video card (had old 120GB hard drive lying around and cousin had an unused media center remote). Sure, there is no warranty, but I've never used a warranty on a desktop PC anyway. I was seriously considering the C-200, but was impatient.
The Vostro 220s sounds about the same as a ceiling fan running and has more flexibility. Sure, more maintenance, too, but I can do Vista Media Center, Hulu, Netflix, CBS.com, etc.
If it had been out in July as original planned, I would probably have ordered, too.
Good luck and I look forward to hearing reviews.
