I almost bought one. But then noticed that Inno's ship July so the global hashrate will be much higher even if I'm the first that gets his hand on a Z9.
What I did last year was buy a miner then resell it. Just one not more to dry the supply like some do. But this is too expensive to take the risk. I profited on the L3+ about 2k euro but I went even on the D3 last year. If this was about 2kUSD I'd buy it.

Plus I'm hearing is just 2 OCed minis. Getting 2 minis for the price of 4 is a pretty bad deal.
