The reason I went with the S1 is just to figure out all of this mining stuff and works out the kinks, after I get familiar I'm going to invest in a very high end machine.
You'll get plenty of folks that pop in with shitty grammar partially explaining why you are an idiot and why you should've done ______ and not done _____ and instead do ______.
Same boat, got into it to learn. And learn I have! I'm sitting on a ton of gear and tho I've lost money and am losing money, you cannot put a price on what I've learned. I've always wanted to just have computers work. I don't want to log in, configure, find IPs, reset... any of that shit. Just fucking work. And I've now learned quite a bit and gotten deeper into the problems when typically I'd find someone smarter than I with a background and ask for their help.
Presently, partially from home, and partially from a friend's, currently running over 2 THs with S1s. Be careful with your PSU choice, yours is on the very low side. Good luck and have fun!
After getting things running, spent today setting this up

have fun!
