I'm new to Mac and considering buying a mini to hook up to my living room flat panel TV. In addition I'd like to set up an Airport Extreme Base at my PC in my bedroom and attach an external USB hard drive to the Airport so that it could be shared with the mini in the living room. My main question is will the 802.11g WiFi standard of the mini be enough to stream large files (like videos) from the external HD? I've considered the AppleTV because it has 802.11n WiFi, but I like the idea of the mini so that there's internet available at the TV.

Just wanted to get some thoughts on this and see if anyone here has any experience with the mini's WiFi streaming capabilities.
