this is the crux of it all. RENTING bare metal (eg from hetzner) is 10x cheaper than aws ec2. So, I can only imagine how much cheaper it is when you buy the hardware directly.
Add to that rackspace costs, staff time doing installation (or cost of remote hands etc). I don't have our figures for rackspace costs, but staff time is fairly low — an hour or two when the server is purchased and later thrown out, and maybe the same to replace a HDD at some point in the 5-8 years we keep it.
Also add the time to get competing quotes from Dell, HP etc and decide on the configuration, but then a similar process is needed to choose from Hetzner vs their competitors.
But they will muddle bits and bytes, nanograms and milligrams, volts and amps and they barely even seem to notice that they did it.
The Guardian refuses to write the degree symbol for temperatures, for example, and have even put this error into their style guide.
