Arrived yesterday! Honestly, if this guy told me they were brand new and never used, I'd have definitely believed him. It all looks like it's never been touched before, let alone used for mining for months! No dust or fingerprints or anything! Definitely in great shape! Most parts were in their original box and anti-magnetic bag (and those that weren't in their original box were still in their own individual anti-magnetic bubble-wrap bag.
Anyway, I bought two of these miners and assembled them, and they're chugging along at almost 2.4 GH/s. I'll be keeping a close eye on everything this seller has available! Definitely a great seller!
