It is exponentially more difficult to deploy, needs more power than an sp10, doesn´t come with a PSU and takes up more space which transfers to higher hosting costs.
Management is also more difficult than with an easy web interface.
None of that is true besides having a better web interface if that matters to you.
Power usage is about on par with sp10.
It is not exponentially more difficult to deploy. Looks quite stackable.
Any good hosting will charge you per electricity usage not space. Not that you would need to host it as there should be no problem with noise if it only requires one or two large fans.
