The 32 individual hash units will be individually bubble-wrapped inside the case, during shipping, to protect from damages. You will need to unscrew the chassis cover, unwrap the hash units, plug them in, reattach the cover, boot up, access the web interface, and configure to point to your favorite pool.
Will these be shipped via USPS, UPS, or Fedex? What service? (ground, priority mail, parcel, etc)
