It's not that complicated, especially if you download pre-prepared images
- that's most of the work getting a new image done. I have a selection of
different distributions (Debian, Slackware, Fedora and Ubuntu, from
memory) that I can boot into a "fresh install" setup, and then modify from
there on in - it saves me a lot of time.

OpenOffice and Firefox can be real memory pigs, though. Gimp can also suck
down a fair bit of memory for larger images, and also use a hefty chunk of
bandwidth for shuttling the display to the client.

Yep, that makes sense. To start with, you can recycle some of the older
hardware as a proof of concept, but once you take it into production you
should really buy a new machine.
To give you an idea of ballpark pricing, you can buy an HP ML350G4 (1GB,
Xeon 3.4, SmartArray RAID controller) online for $2724, and 72GB U320
10KRPM drives are $422 apiece. An extra processor is $974. This is a tower
configuration - I'm guessing it's a non rackmount environment.
On the client side, tigerdirect.ca have off-lease P3 550/128MB systems for
just over $100. It doesn't say if the onboard NIC supports PXE, so you may
need a PXE NIC, and it also comes without a display. These boxes are cheap
enough that you can have a couple sitting around spare, so if one dies the
user can quite probably swap it out themselves and leave the dead unit to
one side until it can be repaired.
