I have purple ones because I'm an Admin here. Comes with the title. Not sure why...
And the specialized hardware isn't too expensive, at least at the entry level. I picked up a couple little Ant miners a while ago for ~$20 each. Not sure what they are now, but there are some cheap entry options if you're interested. Of course, if you're not interested, then this is a moot point.
Welcome to the team.
Yeah, had everything up and running nice and neat in the new datacenter. Distributed between some 30A 208v circuits. (or so I thought). I'm nicely remoting in that night with a cold beer, getting stress tests underway to make sure the HVAC and power are good under stress. Loaded up about 80% of the machines on SAT@Home until they disappeared on me. Poof they vanished from my remote desktop windows.
Then I got everything fixed up the next day. I was minding my own business winning the Denis@Home challenge until Mumps came in and ruined it for me. Again.
