My current home theater solution (Boxee Box) is on it's last legs, and I'm looking to build an HTPC to run XBMC. As far as XBMC, I'll be satisfied as long as I can play 720p, which is trivial. My bigger issue is running the netflix desktop app from the compholio repo. It runs flawlessly on my desktop, but on my first gen Atom/Ion netbook it's unwatchable.

What's the most minimal hardware it will run well on? It doesn't have to be flawless playback, but it needs to be respectable.

I've been considering either but I'm concerned about whether or not it will have enough horsepower for netflix. There are several others that have next gen ION and/or faster CPUs, but the price goes up quickly.
