I just have a mac mini that boots into Plex or XBMC (I've been going back and forth between them) and all my wife needs to operate it is an apple remote control. Gets top WAF marks.
Of course you'll need external storage, for which I have an unraid server that works beautifully.
If I ever decide to game on PC I might get one of those Steam boxes provided they form factor is close to the mac mini and they're completely silent.
I've thought about a mac mini. I have one currently as a desktop, and when I upgrade that may also be an option, but I like the idea of some of my steam library being available there too.
I also have an unraid server - currently 9TB, and I'm considering adding another 3. Absolutely beautify (and Tom just posted an update. Damn. Just updated last week). I built it out of cheap hardware, and most of the cost was in the hard drives.
I just see this as the alternative that gets me a real PC connected to my TV, with XBMC and support for games in a much less hackish way.
