This build is mainly parts from my old gaming PC and NAS so it really did not cost that much to build.
The new parts were essential to the build were:- PSU, CASE, HD cadies, GPU and SATA card.
With these new parts the unRaid OS allows for a single drive with the data/movie and the cache/program SSD to be running to watch plex at approx. 84 Watts but when all drives spin-up 280 Watts and settles at 189 Watts so using an 600 Watt PSU will handle with the initial spin-up load and the PSU fan turns off when not needed.
