I like that it’s in a 3U structure, so I'm able to rack it with my existing structure. I confirmed serial numbers with Bitmain, and so they matched legit generation batches. Can’t recommend this miner enough. The store can be super Experienced—they answered just about every pre-sale problem clearly. https://buyantminers19pro43163.yomoblog.com/46458181/quick-guide-to-bitmain-antminer-l9-16gh
