The cable on top of the disk was glued on quite well, I spent 10 minutes getting it off without damaging it. That was the hardest part of the whole operation. The rest of it was straightforward.

Thinkpad x201i with Thinkpad branded sleevecase and extended 9-cell battery (still fits in the Sleevecase)

A wonderful little compact powerhouse. (the X220 even comes with an i7 option!) With 9 cell battery can last you about 13 hours and still very light to carry.
I prefer the T5xx series myself, but could easily settle for these x2xx models.
