Received my E3. Appears to be hashing at 2/3 capacity; pretty sure one of the hashing boards are DOA.
Compared to a friend's E3, it appears to be missing 3 of the 9 chains, so that would make sense.
Guess i'm lucky, got it today, at least it's not DOA, we'll see how it goes.
The miner seem to do interesting things for a while before starting mining, and use about 50% of its normal power use, but doesn't hash for a while. I'd say it last about 8 minutes or so. Its sitting at 770w atw. For 800$+ it seem pretty good for usual prices.
