antminer did the same with s-1 s-2. if this unit does 5800 khs with 16 x 5 it is like 16 grid seeds getting 362khs each.
if you can get 5 grid seeds for 651 from gawminer so 4 x 651 = 2602 for 20 miners.
so even if you need a 20 port usb hub
power bricks and lots of wires for the same 2,995 running 20 x 350 or 7000khs is doable. power will be about 180watts.
Now if you buy s-1's and s-2's the same better price for a mess of smaller parts does apply.
Right now I have 7 s-1's 20 gridseeds and 5 more on order from gaw I will total 25 girdseeds. and a wicked mess of wires power bricks and psu's and I saved some money over 1 s-2 and 1 grid seed blade
