Now that's a miner I've not seen in a while. I had some of these that I'd overvolted with a resistor mod and some extra heatsinks on the VRMs and was getting 7.2MH or so from them a long time ago. Good little miners.
I got 2 of them sitting around in their boxes somewhere =) ... yes very fine little miners! I may lottery mine w/ them someday. I did the same mods to mine =)
