Howdy mining community! Ive recently gotten into mining using nicehash on my pc. I had a few questions I was looking to see if you guys could help me with. So I picked up 4 asicminer block erupter usb 330mh/s and I was planning to use them with a raspberry pi. The only thing is I have a plan to use my raspberry pi for something else, and I have some old pcs laying around my house. Does the specs of the pc really matter for mining if I am using block erupters for the mining? And if the specs do matter, what are the minimum spcs the pc I'm using be running? Before you say it, I am 18, I don't pay the electric bill so where as I have read that they aren't profitable on the long scale if I was paying for electricity im not so should not matter. (Just using this to learn more about what I'm doing) Also, could someone point me to a good tutorial on how to set these things up with a pc? Next, should I be using nicehash on my main pc to mine when I'm not using it or is there a better program that will generate me more that I don't know about?

                              Thanks A bunch,
