The TAM was really a mix and match of several existing products:
The board was a modified 6500 board, the screen was the Pwb 3400's one, the keyboard coming from a 190/5300/3400 PWB, as well as the trackpad probably... all in the unique 20 th AM casing.
PSU was a modified Powermac 6400/6500 in the Bose enclosure.
