Those first-gen MacBook Pros turned out to be pretty miserable lemons when my workplace bought them; I actually held onto my 1.67Ghz Powerbook until almost 2008 because of the teething issues. All sorts of overheating and wireless problems mostly, but there were a few that also had this issue with the DVD ROM drive jamming if any pressure was applied to the wrist rest when it was spinning. That couldn't help but make me laugh because I hadn't seen that issue since the first generation Titaniums.

That said, not every one of them was bad and they did perform decently well. Keep yours cool and hopefully you'll get a few miles out of it.
