How to replace the motherboard of a computer

The computer I bought during the pandemic in 2020 had an entry level motherboard: an ASRock A320M-HDV R4.0 with limited tuning options in the UEFI  BIOS. There was nothing wrong with it (after I updated its BIOS to solve some random video games issues), but I had always wanted to replace it with a model with more tuning options. I didn’t want to spend a lot of money, so I ended purchasing a refurbished Gigabyte B450M DS3H motherboard (36€). I have documented step by step in this tutorial how I replaced the original motherboard of the computer  by the new one in case you need to do something similar.

How I replaced the swollen battery of my MacBook Pro 15″ Retina Display (mid 2014 model)

My trusty MacBook pro 15 (mid 2014 model) was slowly dying with all the symptoms of a swollen battery: the case was warm, the fans were blowing at full speed even when the laptop was not performing any CPU consuming tasks, the trackpad was not working anymore and I could even see that it’s back was not flat anymore. I was mostly using it connected to a screen, with a wireless trackpad and keyboard, so it was not such a big issue but I was starting to fear the battery would explode or catch fire.
