So I have a unique setup and I was going through some of the older posts, but figured I would create a new one, because this topic often changes. I fell into an opportunity to access unlimited free power for the next few months with minimal cooling costs within a business office. I don't feel comfortable investing in a proprietary miner, so I was looking to create a CPU/GPU rig. I actually work for an IT supplier, so having access to the parts I need might be a little easier than doing it retail. Nothing crazy expensive since I am so new to this, but I wanted to know if there are any general suggestions on how to yield the biggest buck.... is Ethereum profitable? or shoot for other alts, and what does the mining landscape look like 6 months from now (just trying to get a better idea of ROI) because if its a coin I believe in, I may scale it up to a potential large setup. Any suggestions is appreciated.
