Mining equipment = old CPU's used to mine BTC?
Already have an old HP desktop laying on the shelf to take the place of CPU Mining
Im guessing your after ASICs only? If not what else would you consider?
Not exactly, I already have a small GPU rig, depending on what you have and if your willing to sell it for the price of "Something that doesn't do it's job anymore" I'd be willing to buy just about any mining equipment. FPGA, GPU(Would like a full rig not just a pile of GPU's
), ASIC, Litecoin/Scrypt ASIC
