A month or so ago, I looked through the list of refurbished MB's available from Newegg, and saw several that run the old PC-133 SDRAM sticks. But a check just now drew a blank.
However, for $69 plus shipping, you get a mini-tower case, Soyo KT-133 MB, and even a power supply, at

I didn't take the time to see "how old and slow" of a T-Bird it would handle.
Additionally, there was a list of 8 sources for MB's with the KLE-133 chipset (related to the KT-133 somehow), most of which were selling the same model MSI MB, but there also were two Biostar sellers, and two Soyo sellers offering mb's your friend can look at:
