I rescued this Pentium 4 from the landfill a couple days ago. I initially intended to cannibalize its 3"1/2 and 5"1/4 drives, but upon closer inspection, it also had a DAT drive, a DVD burner and it was a pretty nicely specced machine for its time - 2005:

It was running XP Pro and I left it there, because why not. But I also installed 32-bit Debian on another partition.

I tried running Gnome but, although it's usable, it's slow enough to be annoying.

i3 however is no problem of course 🙂 The machine really is no slouch: I was planning to keep it around to read dead media formats, but I might in fact use it for something or other for real, because i3 really makes it decently speedy.
