We just test piloted a few for the first time since IBM stopped making them. I was really disappointed when one had a fan problem just outside of warranty, I went ahead and cracked it open. It was all Phillips screws which was kind of nice. They weren't all the same which kind of sucks but not that bad. I went to pull the fan out to get a replacement, found out I had to replace the entire fan assembly heat pipes heat sinks everything. I was super pissed off until I found out I could buy the part off their website and it was 80 bucks. Dell won't even sell me parts. 80 boxes a lot to pay for a fan, But when replacing it replaces both the CPU and the GPU fan and gives me fresh radiators, It could be worse.

From a corporate standpoint I'm a fan.

Working at a computer shop, Lenovo ThinkPads are usually pretty fine, but the main fault we've seen with them is lack or completely missing thermal compound. On one occasion I saw my colleague's machine not post, and IIRC we had to reset the CMOS to get it back up.
