AntMiner S1-Shipment starting from Feb 28th - Difficulty: 3,620,000,000

Yes and no. I sold a couple of obsolescent miners on ebay for good prices and I never had a problem. But seeing other people having problems encouraged me to stop selling that way. I've also sold old miners for BTC payment and in person cash sales. You don't get as much as ebay, but you still get something to offset the lifetime cost.

I don't know the ebay rules exactly. As I said all I can report from personal experience are good sales where I got paid for the minres and had no problems. And I've sold plenty of other stuff on ebay without trouble (just my own used stuff, not as a business). Miners seem to attract shady people and/or professional scammers.

Those are IBM 24R2640 39Y7169 xSeries 336 585 W, but I wouldn't recommend them as they have the female connector on the PSU and require quite a bit of work to make them fit. Pay attention that you find some guide on how to convert your PSU before you buy it, also some units don't have the fan integrated (older HP).

^yeah, its weird because I just dont see a unit making more than 1.3BTC between march 2nd and its obsolete date sometime in the late fall, unless bitcoin difficulty jumps all stay around 15-20% during that time

how many degrees F would you say one Antminer increases the temperature of a small bedroom?  Two Antminers?

2 Ants & 5870=85 F overnight,when the door is closed 

I doubt it's transferable coz you apply it when you place an order.
If no coupons are in your My Coupons section then you have no coupons to apply.

They're sold out now anyway
