I suggest you rent it out and earn much more:
http://leaserig.net/index.jsp?t=1Current payment is 0.00035 BTC/GH/day. If you bring in 1.7 GH/s, it will generate you a whooping 0.6 BTC each day
nobody will rent at that price because they will never break even...
based on thegenesisblock with 1.7 TH/s (or 1700 MH/s) you should get around 7.3btc per month...(incl cost of electricity) /30 = 0.243 btc each day... this is only for march...in april there will be only 4.3 btc ... and so on....
also renting 8 antminers s1 you only paying 0.28 btc...(50% less then Terraminer)
This is view only from person who is looking rent a rig...
