To the point of TCO including administrative costs, it is interesting to
look at a recent Novell case study around Miami-Dade County. I've provided
some samples of the very interesting article which includes multiple
aspects of TCO.

The county's IBM mainframe had already proven itself a stable and
cost-effective platform for many years. "The IBM System z has a small
footprint with a huge payback," said DiPrima. "We have
compute-intensive applications and billions of lines of code running
on the System z. It performs very well, responding to spikes and
heavy processing on the fly. With the IBM System z, there is no
practical limit to what you can do."
To support its growing needs, the county upgraded its two IBM System
z990 machines to System z10, running five z/OS LPARS and two z/VM
LPARS dedicated to SUSE® Linux Enterprise Server for System z. "The
price/performance of SUSE Linux Enterprise Server for System z is
significantly lower than other UNIX platforms," said Anita Nolan,
senior operating systems programmer, Strategic Technologies Support
for Miami-Dade County. "The IBM System z10 also consumes 30 percent
less power over our previous System z mainframe, and orders of
magnitude less than other platforms."
Miami-Dade County now runs Cognos, HostOn-Demand, CCL and Tivoli
applications on SUSE Linux Enterprise Server for System z. Having a
Linux-based open enterprise brings greater agility to the IT
department.
The IBM/Novell solution also helps the county keep support costs low.
"SUSE Linux Enterprise Server for System z provides a very efficient
platform," said DiPrima. "We have two people supporting the entire
z/VM and z/Linux infrastructure on a part-time basis, compared to
more than a dozen required to maintain each of our AIX and Windows
environments."
