What can you do with OLD computers?

I got an old computer (7 years now).
PII 266
64mb Ram
8Gb HD

Think it has win98 on it. It was my very first comp. Now its definitely outdated and just been sitting there idle and off. Seems such a waste. I am trying to figure out what can I make it into. And I am figuring out how to use it in such a way that I don't need to plug a monitor but instead use it using a remote software. First I will delete off Windows 98 that is on it and install Linux to increase perfomance hopefully.

Another ideas was if I added wifi PCi card (if that would be compatible with Win98) I could make it into a comp hifi or something. But adding a wifi card to it also does opens it up to so many other possibilities.

Yes, let's go to the expense and trouble of immersing a PC in oil to get it to run at a blistering 350MHz. Feel the raw power! For the amount of money you'd spend on squeezing that extra bit of performance out of landfill material you could build a whole new PC.
