I'm looking to build/buy a NAS for myself. I currently have a ds412+ from synology and its full/slowing down more then it should, so I need to replace it. I'd like something that can store A LOT of data (16tb or more) and can stream movies/tv shows/music using DLNA or something similar. what are the pros of building/buying a nas? I've looked online but cant really seem to find anything about building a nas (besides the 5k+ types). Any suggestions?
