Is it possible to make the more tricky upgrades (CPU, display, fan) on similar models but from the X-series ? X201, X210, X220? I would love to do it on mine.
At least for the x220, there are display and fan upgrades (mine uses a x230 fan), you can max ram at 16Gb (the manual says 8Gb, but 16Gb works just fine), but the CPU is soldered, so no upgrades on that.
Reportedly there have been people who have managed to upgrade the CPU on the X230, it just requires a lot of time and effort to do it properly, BGA-s are a pain to solder and requires specialized equipment to do it reliably.
