Currently we are providing mining hosting service in our containers - so ROI calculation in this case depends on the terms you give to your hosting clients 
The price for the MMU itself starts from 20k EUR + options.
The ROI when you would pack the container with miners yourself would greatly variate.
For example - if one would place 160 L3+ and would have 0.15$ electricity price - the mining process would actually provide huge losses to the miner.
However, if packed with S9s / Avalon 841s / Z9 with cheap (>0.05$) electricity - the financial situation looks way better.
