X220 from 2012 still rocks!

I just love my X220 from 2012. It runs Windows 10 quite well. I replaced the old Azerty keyboard for Qwerty. After installing a modified BIOS (v1.46 without hardware whitelist) I was able to replace both the Wifi and Bluetooth interfaces for more recent higher speed versions. What else did I do? Oh yes, I swapped the HDD for a SSD and the 4 GB RAM for 8 GB.
