Hey SP-Tech, you've got two customers already for SP20, lets get the ball rolling :-)
3*
+4
We can do SP15, which will be one ASIC board in SP30 2U enclosure with only one PSU.
Better name will be "SP30 home edition", it should be quiet under "Normal" mode.
Due to the management board, enclosure, etc, the cost will be 60% of SP30 and the hash-rate will be 50%
Will such product make sense ?
