Im wondering about the card width. Looks larger than 2x slots and thats the general spacing on most motherboard every second slot for PCIe and very few cases support more than 8 card slots.
Also your right they were using 4U cases in their examples so that still matches.
They really need to give specs like how long, deep and wide the cards are plus details on the radiator and tube length. Trying to work out where to mount everything is kinda important for people trying to decide if they can use these things or a refund is the only option.
Jesus, REFUND. Why are people still contemplating whether or not to get refunds? They shit the bed on delivery. They shit the bed on pricing. They shit the bed on efficiency. BTC is in a slump, get a refund and enjoy the best possible return on your 'investment' even if you're in the red.
There is absolutely no scenario here where if you have the option to refund, you shouldn't.
Note the fine print - refunds in currency or vouchers. Chopperman foresees another shit coming when the refunds are only available as 50% usable currency and 50% worthless BFL money. Chopperman is guessing that it's 50% worth of hosted mining coupons. How's that for a final dump on customers.
