video squeezebox?

Hi all,
So, i am moving to a new (to me) house which is pretty small. I want to conserve space and was wondering if anyone has experience with running ALL of their multi-media though their pc, and, more specifically, using wi-fi to stream audio and video to their 'applicances'.
I have been looking around but have been unable to find the video equivalent of the squeezebox (the philips Streamium looked promising) and was also thinking that maybe i should wait for more to come from 801.11n?
comments?
thanks,
Byron
