i decided to stick with only 2 mining rigs and these are extras. Brand new never opened.
I have 1 of them left. $390 each on eBay. I can do $360 + shipping for members here.
Here's the eBay link for the last one
so, I built my own NAS and with 2x 8tb WD REDS and an i5-7600 power draw is under 30w idle. Currently there's a 600w SFX PSU in the fractal 304 case. Obviously overkill, but the SFX PSU was taken from another system.
Now, I search and search, but I cannot find an efficient PSU for my NAS...
