I probably should add some details to make my post more interesting
Thin Client Wyse V10L - 512MB (upgraded from 128MB), external hard drive
Had to do everything from boot CDs as Wyse does not support USB Boot drives.
Running the bog standard AntiX installation, completely out-of-the-box. Runs very nicely
Had no luck with the puppies, lubuntu, dsl, peppermit, zorin, bodhi, etc. No fault of the distributions, user lack of knowledge probably. I did get Tinycore to work nicely but I could never figure out how to install it on the hard drive.
