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) I'm fairly certain that box is larger than 4U. I doubt it's the production case, however I could be wrong.
2) Interested to see the actual numbers.
3) 4BTC? 5 S1's cost ~4.96BTC, have less chips and no PSU. This ain't a charity.
4) This is no surprise. I'd guess the next model (S3?) Will have a smaller process node.
