Here's a picture of Rig 2, before I put it out in the shed.
https://twitter.com/relay_1/status/290159160987897858/photo/1My total hashing power is 4.5 Gh/s
Rigs 1 and 2 have 1200w PSUs and use PCIe Risers, refer to the picture above, rigs 3 and 4 are just GPUs stuck in the boards.
I keep my rigs outside (I live in cold climate) for free cooling. I don't mine for personal profit, just to break even on gear and electricity and make a little bit of $$ to power the 7 tor relays I operate in the EC2. Anything extra goes back into gear or more relays.
Rig 1, ~1.6 Gh/s
2x5850 2x375 Mh/s
1x5830 270 Mh/s
1x6850 254 Mh/s
1x6950 366 Mh/s
adding a 5870 or another 5850 this week
Rig 2, ~2000 Mh/s
2x5870 2x415 Mh/s
2x5850 2x375 Mh/s
1x6850 255 Mh/s
1x5770 200 Mh/s (on a good day)
Rig 3, ~900 Mh/s
2x7870 2x450Mh/s
Rig 4, ~1 - 1.2 Gh/s
2x7950
