I have 2 S1 to S3 units available. My brother had them and has had them sitting around. 1 runs at 440GH but occasionally needs to be reset. I didn't put together for him so I speculate that it needs thermo-paste and tightening down and would no long need the re-set. The second 1 is missing one of the cables from the old controller to new one. If you have one it should work fine.
Unfortunately I'm in the middle of moving and don't have time to take care of this so up for sale. Want to sell both together so I don't have to deal with 2 shipments.
Submit your offers. let me know if its shipped (if so provide zip code) or you are providing me with a label.
This is the only payment address: 146feyvSJBpoej3g3ANjL3xfhLEvVGc6kU
