Just bought a block cube Erupter from another user and didn't do my homework on what had to be done to operate these. Too damn frustrating for me but great if you already own one or have the patience to configure it. It also comes with a PSU this one

Here are the pictures from the user i bought it from the PSU is just to the right of the cube in pic.
Selling this so i can get some red bitfurys just lowered the price to $50 + shipping U.S.
P.S. who the fuck created these cubes? That Asshole needs his teeth knocked out!
