Hook me up with a few HP Pods and I'd be all set
The HP Pods are self contained data centers in a box. They are basically prewired, air-conditioned, humidified and stocked with servers that are in a 20' container (the same you see on the backs of trucks).
The model makes it ideal for expansion. Of course, you still need IT staff, server monitoring staff and then sales people to sell the equipment. I think as Steve pointed out the "within reason" is something that will trip people up. Is $50 Million within reason, or is $1 Million within reason - depends on what you're getting.
I used to have a Blade system that was really a great system. Price was around $45k for 16 blades, but much like the folks selling the Cloud type setups where you can enable and disable processors, you could do the same with the blades (and that was 4 years ago!)
These days, I'd much rather not have to deal with hardware at all and instead leave that to others and just focus on the marketing aspect of things.
