My cubs are no longer overclocked as of the last dif change. It was generating to much heat for not much gh in my server room. I wont be turning them off any time soon as I just want to be part of the network. But I also wont be getting anything newer unless the mining world gets less completive and I cant se that happening.

Surprisingly I have made just over 1.5 btc with two cubes and I paid .7 per cube. So I may have made a very small amount of money depending how you look at it.
