Wierd, why you are happy?
If you had bought a batch one hashfast rig I think you'd be as bitter towards them as you are towards other companies. Have you read the HF thread?
Also 4 boards

- they only do a one board machine (BabyJet), a two board machine (BabyJet+Upgrade) and a three board machine (Sierra). There is no 4 board machine, unless you buy boards wholesale and build your own.
Lastly, just a slight correctection, Neptunes are "at least" 3TH, given that from initial expectations to final result the Jupiter machines went from 350GH to 650GH there is some small expectation that they will over deliver again.
