So is the S5 still a viable option for mining? I'm not by any means looking to make bank with it just something to let run for the next 3 years of when I'm in college and make some money lol.
I did not see anyone focus on this part but running for 3 years is pretty unrealistic. The S5 is already 3 generation's old at this point, so add 3 more years.... hard to say what will be out. I would say I would not plan on running it for 3 year's as even if it is still in working order chances are it will be very out of date.
Also know the S5 really is not quiet or cool (speaking at running at default settings). So I also am not sure I would want it running in my dorm room. I have lived in dorm room's .... not the best place for a miner I personally left my miners at my home and did not bring to a dorm. Although I think I was GPU mining back them.... been a bit.
But to make it short if you are planning to mine in 3 years in advance I would wait a while to get a miner for that. We really have no idea in 3 year's what current miner's will be like, so lot's of things up in the air.
