Quoted from pezpunk:

i'm putting my mining rig up for sale. it's been really good to me. i'm happy to help anyone out with support and advice (within reason) if they buy it. i think i could ebay it for a lot more than this, but i wanted to give you guys a crack at it before i auction it off.
keep in mind you don't necessarily have to make back the whole cost of the rig -- much like a pinball machine, you could operate it for a while, and then sell it on (or part it out -- those 6 Vega 56 video cards can go a long way towards making your money back).

mods -- i don't THINK i'm breaking any rules with this listing, but if so, my apologies. I thought this was the most proper way to let people know i'm selling it.
PS - i will also accept bitcoin as payment if anyone wants to pay that way.
