This version of my customisable S21 is cooled by a quite RGB hydraulic fan to keep you mining at optimum performance and you can change the face plate to suite your particular vibe. Once its up and away expect a nice 960+kh/sa piece (as apposed to 70kh/s with the Nerd Miner v2) for your efforts and like I say you can log in on a browser to check mining stats (See Screen Shots).
