Have a 1.2 mh/s gpu mining rig for sale. It contains a 650w power supply and 2 radeon 7950. the motherboard also has a port for a third card. I have been running it for a little over 2 months now with no problems. It can be picked up in central Maryland (fully assembled) or shipped in pieces. I'm willing to sell it for around $800. I also have an r9 280x and 2 more power supplies I am willing to sell. $115 for the power supplies and $300 for the gpu.
