I currently have 2x6TB WD Green drives but I don't want to turn on my PC each time I want to watch a movie on my NUC which is my media streamer if my PC is not already turned on. I was thinking of either buy a 2-bay NAS or build a PC and use it as a media server. I don't need transcoding since my NUC can decode most audio/video formats and I use Kodi on it and I just the media server to host my files. I already have a spare DDR3 kit that I'm not using, Hyper 212+ CPU Cooler, and 2x6TB WD Green drives. If I build a PC, It's going to have an i3-4170, 16GB DDR3-1600, 2x6TB Green drives, 120GB SSD. I would still need to buy a motherboard, CPU, case, power supply and a SSD (for the OS). I want to avoid buying Windows and just use Ubuntu if it will be adequate for media server duties to a media client that is running Windows.
