Great rig. I am currently leasing it for an hour so far mining perfect. Hopefully I get that 1 free hour :-)
Sorry, it seems the system only allow me to add 30% (18minutes) of your rental time.
But i will honor this deal. I will refund (42/60)*(0.0087/2) = 0.003btc if you want to.
By the way, I didn't expect people to rent 1 hour for free 1 hour. lol *change the term due to this*
