Thanks everyone for the advice!
I have 4 used S3's on the way I paid under $500 for, going to see how it goes for 1 month. God willing, I'll get used PSU's here soon.
@alh: Thanks for all of the advice. I guess I'm going to have to find a way to keep the office cool.
@notlist3d: Thanks for the advice. I'm going to have to avoid asking maintenance about breakers and such to stay stealth.
@srgkrgkj: I understand Bitcoin could fall at any moment, it could also dramatically rise in price, again. How would you sell electricity though?
@philipma1957: Underclocking sounds like a good idea, thanks. I wonder if I can check with my local electricity provider to see how much electricity they're using. If I get caught I get caught, I'll cease to use the miners and take my loss. No biggie.
@crazyivan: What cloud service would you recommend. I'm more interested in mining myself, though.
@crazyearner: Thats what I'm thinking
The good news is PSU's are good for quite a long time. You most likely will use them for multiple generations of miners assuming they are good quality.
I think stealth is a little odd if you have the right to be doing this I don't see why stealth is needed. But if anyone sees it they most likely will think its computer equipment.
Also good thing is with S3's I think you can run a underclock that will make them not horrible in a office.
