There seems to be no or very little interest on ebay for X1's. If I'm lucky I could sell my one fully working unit for about $100 but my other unit throws a ton off errors and I can barely average 75gh/s out of it. The dodgy unit didn't even work when I got it but I was able to get it hashing after pulling it apart and reseating the cables and hash board. Bottom line is these things are junk and I don't feel comfortable selling them.
Why can't you ebay them? Mine showed up, ima use em until they are sold. I really came to terms about losing this money a few months ago so now i figure even if i can get SOMETHING for them it is still better than nothing.
