In the same boat. After like 15 years I had enough. I've started de-Apple'ing my life in 2024. Still run M1 Pro Mac from work, which is great. 2 days ago I've finally ordered all the parts for a Linux PC, high spec. Not for gaming or so, just for compute. I'm soooo looking forward to the freedom that this will bring. The stuff that I already run on Linux, the distros are all great. I love Gnome for how it looks and KDE for how seamless it works. The new PC will let me tinker and try and hop and swap like I could never dream of for so many years.
Curious what kind of specs you've decided on, would you share? My mind always jumps to EPYC or Threadripper for this kind of use-case
