When I was 12 my dad gave me two defect PCs and says: find out how to compare the working parts and you can have this one for you. Also a copy of win95.
If I look back this was enough to learn about every hard- and software related issue ever. Hell, even the mainboards back then doesn't have any documentations about jumpers etc.
And win95 need a regularly reinstall. If I compare how many reinstalls I needed between win and Linux, windows wins.
