Think infrastructure like a secure building (with multiple layers of physical security), redundant power grid feeds, redundant UPS / power systems, redundant backup generators, redundant HVAC, etc. Keep in mind redundant means at least n + 1. The +1 not only means you need at least one more than required to make things work. It also adds at least 125% to the cost of buying and maintaining each system because you need to have automatic fail-over systems that connect the n and the +1 together.
I can go on, but you get the picture.
This is quite an old thread and probably didn't need to be bumped. But for my input I have to agree that you should first obtain customers and then do this venture properly.
For a success story though look at HostDime, they started out with no clients and grew to just 200 servers which is when they built their first in-famous Orlando datacentre. Now look at them.
