Get the hardware manual from the IBM/Lenovo support site.  It's a PDF so you'll need a reader installed, obviously. ;-) You'll need the exact model code off the back of the case. (The interface offers a massive list of these to select from).  It will take you to the exact manual set you need.  

All the FRU details are there in the hardware manual, plus a lot of other useful info.  Best of all, the last section has the most amazingly fine detail, with diagrams all the way, about how to replace each FRU, including back-links to each thing to remove to get to the next thing...right down to blown-up drawings of things like brackets, screw-holes, etc.

Have fun!
