it's hell old and titanium powerbooks are prone to cracking, which is why apple ditched titanium after the wow factor wore off and went with aluminium. Also note the hinge is missing from the back (probably snapped and broke) and it's interesting to note there is no modem. I didn't know you could get any apple laptop without a modem....?
It'll probably go up to around $400 closer to finish.
On a side note, I have a 1.25Ghz PowerBook 15in for sale if you're interested?
