Title.
I have been mining with this B52 for around a month and a half. YMMV, but it's been hashing at 3.92 TH/s without overclock. The boards temperatures typically stay around 78 degrees, which, from what I gather, is pretty average for these units. These are sold out through Halong Mining's website. Innosilicoin still offers their identical S11 for $3,200 without the PSU.
Ideally, I'd like to get $2,700 for the B52 with the PSU. Please comment before messaging.
Before he asks, no, I will not sell to jrc209. For anyone else, I'm happy to use escrow at buyer's expense.
