Sorry to interrupt the fight but one thing I consider important is details on power supply required so that upon delivery we can all have one ready to go.
Time is going to be crucial especially in the first month with diff increases etc. , you don't want to lose time hashing waiting for an item like that do you?
Personally I'd like to be shopping for mine now and be sure it's the right one.
They would have had to build a unit to report the actual power consumption, so your question would be answered in September.
If you can't get an appropriate PSU from a local PC shop in less than an hour you must be in the 3rd. world somewhere.
