Hey guys! I'm looking for a decent mining setup that could pull about 500 GH/s. Unfortunately buying miners used on amazon and eBay don't include the power supply, and buying one would go too much over the budget of $200 USD. So, I'd like to ask the community if they've got an old asic, perhaps an S3 or an S4... Something self contained would be amazing, because I've never ran a dedicated miner. I have mind, though! I used to run a GPU instance on amazon for kicks, back when they made a few dollars. But I've been into bitcoin since 2011, so I'm well acquainted with it. Thanks for any considerations and offers!
