I am somewhat tech savvy, however it has been a few years since I built a PC from scratch. As for Netflix, on my main TV I will be using my Xbox to connect to Netflix, I just require a streamer box for the other two tv's that can also connect to Netflix, so that my kids can watch Netflix.

Not looking to do any OTA PVR'ing, so no TV tuner is need. Just wish to watch ripped/downloaded movies/tv shows, as well as stream that media content to the streamer devices. Other then XBMC, I have been looking into MediaPortal and Mediabrowser as a HTPC frontend.
