I am developer / database expert. At work I use Linux and Windows, whilst at home I use Linux. I have built 8 or 9 PCs over the years but the last one was completed 10 or 15 years ago, so it was interesting to see how much has changed in that time, and also how mainstream the whole field has become. YouTube and sites like pcpartpicker in particular, have made pc building and modding much more hassle-free, and now I am back in the game, I cannot wait to build my next one!!
