[K12OSN] Anyone quantified savings using LTSP?

I've seen a few use-cases where some claims are made on cost savings
using LTSP. I'm curious if anyone here has looked at this recently at
their own schools.
I was looking at thin clients the other day, and although I'm not sure
the very inexpensive $85 Norhtec clients have enough power, it's
looking like $150-$200 clients are possible.
Our school is considering one option of using the Mac Mini for the
student workstations. So potentially, that's $400+ savings up front
per seat if using something like a $200 thin client. Actually, that
might be an underestimate considering that the thin client hardware
would probably have a longer duty cycle than stand-alone workstation.
Of course, it's not that hard to come up with donated PCs, so that's a
bigger savings.
Software purchase, upgrades, and licensing seem like another
significant per-seat expense. I assume most schools migrated from
Windows, but the licensing requirements might be similar to Apple.
Anyone have any numbers in this area?
Energy savings might be a consideration, too. Some of the thin
clients have very low power consumption. Swapping out 100 PCs with
300 watt power supplies to 100 thin clients that consume 10 watts
might not be a huge difference in cost but not insignificant.
Finally, it's hard not to imagine the management of 100 thin clients
is significantly less than 100 workstation. Still, I doubt that often
results in any savings. Rather just a change in admin tasks. Have
you realized any quantifiable differences in management costs?
Anything else?
