The antminer s3 seems like the best deal at the moment as far as w/gh, but none of them seem to be able to break even. Is there anything I am missing?

I am in need of money. I think I priced my items fairly, but if you are interested please make an offer if you think I am to high.
I have a scrypt farm that I am selling. It consists of 4 rigs, in aluminum open air frames. 1 rig uses 6x 6950 gpus 3 rigs use 6x R9 270 gpus
Each rig runs about 2600khs.
I am asking 10.5btc for all of them including UPS ground shipping to the usa,
I also have 6x Saphire R9 290 Gpus that are new in the box. I planed to build a new rig with them, but as I mentioned before I am in need of money. I will sell them for .75 btc each, including shipping to the usa.

I notice the antminer u1 is significantly more efficient than the antminer s1. Does anyone have a solid explanation for this? I know the s1 controller uses power, but not that much!
Is it just the difference between the conversion of 12v (s1) vs 5v (u1)
Or perhaps the density of the chips to each other vs a single usb?
Does anyone have a slew of them on an externally powered usb hub that can verify readings at the wall?

Hello, I am selling custom built mining rigs. They are setup with 6x Radeon 6950. They have windows 7 professional, 40gb sata hard drive, 4gb ddr3 and use ultra efficient 25watt dual core cpus. They use a corsair 850watt power supply for the motherboard and the pcie. They use a 1570 watt dell server power supply for all of the 6pin connectors. Will sell for $2600ea. Currently have 3 on hand. Will have more built over the next few days. I ship them at stock settings and they run at 24-2600khs. They can hash faster if overclocked and shader unlocked. Hosting and maintenance is available for $160 per month

Hello, I have heard that the xfx brand 7950's are shit for mining. Does XFX have poor performance with there whole line of gpus or just the 7950? Does anyone have an explanation as to why this could be? They all use the same gpu how does the manufacture vary that much in performance? What are some good brands to look for in the r9 290 series? I only ask because I have mostly used 69xx series cards, I purchased some 7950 cards and they worked great for btc, but they shit on ltc. They were xfx series cards. I am now shopping for a R9 290 and don't want to make the same mistake again.

Hello all, I have attempted to sell several items on btctalk and I never get any interest, but I can sell everything on ebay for the same or occasionally more money. I want to support the bitcoin community and I abhor ebay and paypal. Am I doing something wrong here or is there a better place to sell with btc?

Hello I have an asicminer blade backplane and power supply I would like to sell. The backplane is slightly modified to match the power supply it is mated with, however it functions perfectly. I am asking .09 btc including shipping by priority mail to the usa.

I received an asicminer blade and connected it up and I can access the web gui but all of the chips show x anyone have any idea what could be wrong? It would have to be an error from the factory, I have purchased a whole lot of blades from this seller and when I received it it was still sealed. I know that each bank of 4 chips has one regulator, 8 regulator circuits per blade. I would think it would be unlikely that they all failed at the same time. Is there anything they have in common that could fail? any thoughts on things to check would be appreciated.

Hello, I am now in bit of a pickle. I reserved a spot in a group buy, assuming no big deal. I setup an account at btc-e to trade some ltc to btc. Btc-e made the trade easy enough, but now they say I need to wait 3 days to withdraw my btc. Is anyone willing to make a loan for 2.25btc for 3 days, and what fee would you want for your service? Thanks

I am suspicions about KnC. They have a good product with a good design and the units are fairly efficient compared to what else is out there. They really have the top of the market. Why on earth are they abandoning it for a new preorder product?? I also see they have discontinued use of paypal. It makes no sense to me. A KnC Jupiter is going for $20k. They have everything already, just make some more!! Why do all the mfg feel they need to screw everyone around with preorder crap!

With the upturn in btc price I had a miner that was selling for 2.5times what I paid for it on eBay. So I sold mine. I had to pay $70 to ship it and the buyer received it 3 days later. 26 days later, the buyer opened a dispute claiming that it didn't work correctly. I replied that it worked just fine when I shipped it. Ebay gave him 10 days to open a claim or close the case. 10 days later escalated it to a claim. Ebay took 2 days to make a decicion and now says he can mail it back for a full refund. They gave him 10 days to provide tracking information. It is now the 7th day and still no tracking. He probably wont ship it untill the last day. Then it will take another 3-5 days to get back to me. I am out the $70 for shipping and he has been mining with my machine for over a month for free.

Hello All. I saw over in the hardware section openrigs.com is selling a case for pcie video miners/superman bruteforce rigs. It appears that the gpu cards are hanging by the back plate. It also apears the motherboard is hanging from the 3 screws on the one side. All of the rigs I made I support the back end of the cards. It seems to me that way would put too much tension on the cards and motherboard. Anyone have any thoughts or experience relative to that mounting style?
