I have 4 of these that I'm putting up for sale and thought I'd ask here first in case anyone was interested. They were used to mine for about 1 month at stock clocks. Ran flawlessly. Used them in the last Einstein team challenge that SETIUSA participated in. These cards are really well made and come with a factory installed back plate. Come in the original box w/accessories. Looking for $100 each shipped. $190 for 2, $285 for 3, $380 for all 4. PM me if you're interested. Thanks
