I'd probably look into buying some of these if I had any coin to spare. We have something like 16 S1s still running around, custom undervolted - pretty nice machines. A dozen will run on a single DPS-2000bb with headroom. If anyone buys a stack and can get them to Missouri, I can host 'em and also do undervolt/underclock. According to my tests (
https://bitcointalk.org/index.php?topic=857967.0) they'll get below 0.8W/GH board-level, for what that's worth.
To the seller - hope you get/got everything ironed out and not get beaten up by the hoster.
