I just picked up my first iBook Clamshell. I've been wanting one for a while and I'm loving it! It's the 466mhz FW SE model. 576mb ram, 20gig HD. The hard drive is a bit noisy, but I plan to upgrade it eventually with a SSD. It's running 10.4.11 right now. It's fine, but lags a little bit. I want to experiment with linux, os9, panther and tiger and see which I like best. It's possible that I might eventually set this up to boot all 4.
