Diskless or truly thin (remote execution)?
Also remember that a typical 2.5" drive only uses 2-2.5W of power,
far, far less than even a typical, low-end chipset, let alone the
12-20W of a typical 3.5" drive. Even 10-15,000rpm 2.5" drives use
less power than commodity 3.5" 7200rpm and even "green" 5400-7200
variable 3.5" drives.
The cost savings is really in the TCO more than power. I've been
through this ROI game with numerous fiscal and retail customers
over the last half-decade. Typical PC TCO is $500 just on the
servicing, which makes diskless and, even more so, thin clients
a major sell. The power difference is less than 1/10th that.
In all honesty, running with ARM instead x86 (instead of Atom as
well) is far, far more of a cost saver. There are several new
NAS appliances hitting the market now that are a low-power ARM
with dual-2.5" (not 3.5") bays. Small in size, and they run on
12V @ 2A, typically sub-20W total.

People confuse virtualization and remote desktop. No one advocates
virtualization over a remote mount. However, virtualization providing
a remote desktop is a whole different story. ;)
Red Hat bought the upstream maintainer of KVM for more than just KVM.
Although control of a major upstream componen tlike KVM is trademark
Red Hat, especially when the vendor is dabbling with proprietary
software (and Red Hat wants to bring a quick and complete end to that).

I don't have a "favorite Linux distro." I use, develop
and support community efforts, often built around Linux.
Technology and solutions are my focus, not dragging in
assumptions, marketing and other concepts which dominate
non-community developed software, which I left long ago.
