Qnap

I'm looking at QNAP or Synology to setup a NAS/home server. What I want do is be able to stream 1080/4k video to multiple sources at the same time. I have Vizio and Samsung TV's some of them are 4k. I also have cell phones,tablets. I want to be able to watch these videos from this NAS anywhere...

qnap recently released their hd station (video for reference http://www.youtube.com/watch?v=Xu59r_MrVag&list=UUoRW41xIvQXqUW4B4QCqPgg&index=2 and more info http://www.qnap.com/hdstation/us/ Is this a viable option to skip your media player? I think its really cool how you can directly plug in...

I am considering buying a QNAP TS-219p II to back up either system images or just folders for 2 different computers, as well as for streaming videos. I was planning on using Windows Backup Utility, but I only have Windows 7 Home Premium, which doesn't support network backup; I'd have to upgrade...
