You could get 3Th/s shipped from stock until last week for only $5,600+shipping.
What's the big deal ? You could get 3TH of in-stock S2 with free shipping last week for $4950 and you wouldn't need hearing protectors or asbestos gloves. If you're not too worried about power, 15 S1 OC'd to 393.75 will get you 3TH at a LOT less.
I'm amused by the way SP talk about spreading the hash then build equipment that you wouldn't want in your home or small office.
The big deal is that the Neptune isn't worth the money right now. 3TH for 10k+$ is simply not worth it.
SP10 is for a DC or for the garage/basement.
Currently , S2 is much more expensive and with much higher consumption.
SP10 is ~ .89kw/th, SP2 is ~ 1kw/th . I wouldn't call that much higher consumption.
How much extra do you pay to host a SP10 in a datacenter ?
Re price: ask and ye shall be surprised
SP10 can do 0.7kw/th. SP2 can't do that.
