Genuinely curious: Given that Softlayer bare metal server prices start at 700$ per month is there even remote chance of this actually being profitable?
Nope, that would be hugely unprofitable. To give you an idea:
The P100 instances on Softlayer would cost around $2,000/mo, and would generate approximately $170/mo in ETH when fully optimized. One could probably build a DIY rig with the same hashing power for less than 2k total.
