After reading lots of posts about upgrades I treated our old T420

I bought this old T420 refurbished several years ago and we used it when abroad or for TTRPG. It just hit a barrier at some point (notice Rimworld on the desktop - that was really lagging at times) so I dived into upgrade posts on Reddit and videos on YT and ordered some stuff from AliXpress

Added an SSD, more RAM, new I7-2760QM CPU, cooling pads and a larger capacity battery. Was all done in a night's work and am pretty happy with the result. Not sure what to do with the DVD drive, for now I'm leaving it be. I guess I could add in another SSD but that's not really necessary.
