1) Sure, it can be easily upgraded.
2) Not sure now, I will update when I know the answer
3) Not sure now, but around $2000
4) We could return some money for compensation if we could not ship out before May 10 (not delivery date, take a few days for DHL). But the possibility for delay is almost zero.
5) In 1-3 business day for processing.
6) Not sure, the possibility is you will have the access.
Skyfromwell will give a formal updated answer later.
Update:
4 modules $8000
A few questions:
1) Confirm that the 1 or 4 module offerings can be upgraded to the full 6 modules with the addition of hashing boards, and that other than the fewer hash boards there is no difference
2) Further confirm that the power supply on the 1 or 4 module offerings would be sufficient to power the full 6 modules if added later
3) Confirm that you plan to offer hash boards individually as upgrades after the initial system orders are filled and provide estimated pricing for such upgrade modules (remember, KNC played the upgrade trick and then never offered price competitive upgrades so it would be helpful to get a commitment from you). Presumably pricing for 4 modules would be less than for a 4 module system .. how much less based on current pricing?
4) If miner is not shipped by 5/10, will you refund the 10% deposit?
5) When you call for payment of the other 90%, will the units be shipped next day after payment in full?
6) Is the firmware root accessible? E.g., can I log in/SSH as root to be able to tweak and upgrade the miner software or is it locked?
