My first home computer was a ZX81, later replaced by a Spectrum 48k, replaced by Amiga 500, followed by an A1200 which I heavily customised by hacking a PC case back panel apart and re-assembling to fit the back panel of both the A1200 MB and Zorro board and gfx card (also had a 68060, IDE interface, MASPlayer and soundcard in there), until I eventually built an x86 system. Originally had XP on it, but also ran Debian.
That original build is still in use, though it's a bit like Trigger's broom, now (https://www.youtube.com/watch?v=BUl6PooveJE
). There's nothing left of the original build, but it's been upgraded component by component as needed. Windows was dumped a few years ago in favour of Linux exclusively. Originally Debian, followed by Ubuntu very briefly, Mint for 3 - 4 years, LFS for a few months (damn, that was maintenance heavy), and now Arch.
Total time to today since the original, about 33 years, and for the first time, I'm considering on buying a new, complete system.
Headless PI. OMG, someone cut it's head off. Oh, hang on. it didn't have one to start with.
