4xS2 Units arrived today.

Two of the four boxes very worse for wear. One box was wet across the end as if it had been sitting in water.

Each machine had a few boards out of the rails. One had it's internal network cable unplugged. Another one had the screen unplugged. One power supply had been badly installed and two of the screws had stripped. the PSU wis sitting at a bit of an angle.

Only received rack mounts for 3 of them.

Reseated all the cards and they all ran fine. No sign of any water getting through the bubblewrap.

One board out of all 40 is showing a zero temp reading but is hashing away regardless.

Unexpected Bonus: They came with Australian plugs!
