Hey... you can get an Avalon unit to do 720 GH/s. It's totally easy. Just put 12 BFL singles in the case. Just a bit more wattage than a 4 card Avalon and you'll have room to spare AND you'll get almost 3/4 of a TH out of an Avalon.
BTW, for creativeIdiot who keeps bitching about BFLs power estimates, I would like to point out that power estimates exceeded expectations for the Minirig. So if you want to talk track record, it's a wash. So stop with your lies about how we've never estimated power properly. We made ONE (count it), ONE mistake and you've been banking on it forever. Of course, you just can't be bothered to mention that the minirig power estimates came in under spec, for which we over delivered on promises. God forbid you tell the truth in all your bullshit.
blahblahblah .... all piss and vinegar...

No one is listening to the rubbish that spews forth from the opening at the top of your body....
