That was probably before power became a big thing for servers - in
most cases now power and cooling are the limiting factors for
expansion in a data center.  Most of the new servers use 2.5" drives
and while they might still use as much power per 1u of space due to
using more blades in a chassis or having more CPUs and RAM, we get
much more performance from the same space and power consumption.
It's not such a big deal for desktops, but you can get small low power
systems if you look around - or just use a laptop that will sleep when
you close the lid.
