I'd really advise you guys to build a low budget/low power* file server if you are going the NAS route. You can save a gang of money in the long run and it just a shyt load better.
@newarkhiphop ,
You are going to want a wired connection breh. Streaming 1080p over wifi via Plex can get ugly real quick. I've done it before and it doesn't compare to a good wired connection. I do run my cables in the walls and under the floor which I know isn't an option available to everyone.
It also depends on the rips you are streaming though, all of my movies are 8GB and up. I know some of you guys like downloading them smaller shyts which shouldn't be a problem over wifi.
