they were on free power, and even the power at my datacenter is super cheap , that being said i finally took down my s2's a few days ago and replaced them with under clocked sp20's , the sp20's came out of my datacenter so i figured i would replace the s2's with them so i can dbl the hashrate at the free power location


as much as i hated to do it ive been stripping down the s2's and parting them out , psus , fans , beagle bones etc , i might hold onto a case or 2 just to see if i can repurpose them for anything , been thinking about seeing if i can stuff them full of s7//s9 blades with an ibm 2880 psu to make a nice rack mount case. but thats not real high up on the last of things to do
