they are working but im only getting 20 TH/s with three of them going. I was getting upwards of 40 with the setup that was on there prior to my breaking it. and yes i live in central washington where the electricity is 2.8 cents/kwh.
UPDATE:
well i effed around with overclocking and burned out a couple of my power supplies. now i only have one of my miners running but its getting a good hashrate considering how old it is. .

$0.028 KWh I'm jealous.
Tough call as to buy new power supplies with the 1/2ing coming.
If you can reuse them on something else after might be worth getting a couple.
If you can't you will never ROI them.
I don't know if you can sell the units themselves. Considering you can get a new very quiet 4TH (ish) 160Watt miner with a power supply for $130+ shipping selling something that does 11TH (ish) but needs 1200 watts and has fans that are loud is going to take a while. People may want them because those old miners were just about indestructible and were fun to tinker so you do have that as a possibility.
Personally if I had the space I would keep them to tinker with.
