T520
The T520 is the third model in the T5xx series and was manufactured from February 2011 to December 2012. It is a large, but by no means clunky device.
I rescued my T520 from being scrapped. It was considered defective - but only the keyboard, RAM and a battery were missing. It has one of the much more powerful quad-core CPUs and an additional graphics card. The RAM has been upgraded to the unofficial maximum.
However, the fingerprint reader seems to be faulty, at least under Linux. It is recognized as a new device every few seconds and thus also slows down the system:
