Hmm...
1) Big Box
2) 1000W PSU for a 1000W Draw... Explosion in 3,2,1...
3) Pricy... 4BTC would have been a way better price
4) Still 55 nm chips
A bit disappointed. I wish bitmain stayed online to answer a couple of questions, especially on the PSU front.
1) Im sure that the box is a prototype. the final design will probably be a bit smaller to fit a 4U standard, and anodized/painted to look a bit more professional.
2) Its very likely that the draw at the wall is 1000W, and/or low enough that the PSU has sufficient headroom. it seems unlikely they would miss an obvious technical limitation like that
3) I agree. Price should be roughly: 5x antminer (probably around 0.85BTC by april 1st) + $200 PSU + 15% premium for lower power usage = 5 BTC.
4) who cares, undervolting them clearly does wonders for the efficiency
If these were priced at 5BTC, I would buy 1 or two. but at the current price, it makes more sense to go with the more modular antminer S1
