I bought the dead tree version of this book back in ~2006 or so.

I used to work in a business park in Seattle and the company next door to us operated a PC recycling warehouse. There were piles of old 386/486-era PCs in various states of disrepair just piled up behind their building. I'd go out there once in awhile and pick-through their piles looking for Intel CPUs, sticks of RAM, and hard drives. Find a good chassis with intact motherboard.

I loved putting that stuff together and installing Linux on those machines. I cut my teeth on Linux and LFS building computers out of those Frankensteins.
