We found out that dropping the SP20 package may cause the boards to shift.
We got complaints from about 2% of non palletes customers. Most of the units can be fixed at home by replacing the boards.
We halt individual package shipments for one week, until we'll solve the issue.
If you got such SP20, contact support@ for miner assembly guide. If the SP20 was actually damaged, we'll RMA.

Noticed that the boards sat at an angle inside the case, so I opened it up and re-aligned. The boards are not screwed in or secured with anything except some grooves raised up from the enclosure. Pretty cheap design, which is prone to board shifting if handled rough in transit....
