I'm not an expert, but I imagine that in many cases, capex is not the
limiting factor. In data centres, power appears to be the main limitations -
modern x86 servers use so much power that many older data centres cannot be
stocked at very high density (because the don't have enough cooling for that
much heat).

So the number of boxes you can put in is directly affected by the amount of
power they use. For this reason, the most efficient way is to find the ideal
combination of CPU, memory and disc to do what you want with the least

I guess ram is pretty cheap on power - I mean, it uses hardly any.
