They are from around May, only mined about half that time and weren't overclocked pushing about 620 out of the box. They are extras that are just sitting here - Looks like about $220 on ebay and bitmit. PM me or post, I have around 8. I'll get an exact count in the morning, but it's more than 6 for sure
They look like this. I don't have the boxes anymore, but I have the UPC's cut out, so you will have the matching serial number sticker and UPC if you need it. I'm in the US, so it's probably pointless for anyone else. I'll send you the two power cables for free, I also have a shitload of risers laying around, both powered and unpowered x1-x16 and x16-x16
