Many excellent points and the one of interest is power usage - it'snot just the cost of buying the kit, but also powering, maintaining (admin) aspects. So the Bottom line of ownership is far bigger and as you say, you really need to get 100% utilisation to capitalise in that level of outlay. Hence the on-demand cloud option on many levels becomes cost effective, even if it does seem not cheap. Sure it is not cheap, but overall, it can and does work out way cheaper for many use cases.
Makes you wonder what kind of power costs you would incur running one 100% utilisation. Certainly even with best prices, be looking at several thousand a year I would of thought, that's not even factoring in provision. Which would mean 3 phase power for that type of load and then you have to balance out the phases. So many little details that become more an issue when you start getting to datacenter level power usage. Then UPS load/capacity costs/planning, networking. So whilst the costs of these units are high, the other costs that add up, sure do add up fast.
