Don't feel too bad. I built my first beowulf cluster out of my dad's cave of obsolescence in the mid-90's... pentium II's and older. nobody noticed the giant networked-cabled-monstrosity with cables going all over the basement until he got home and wondered why his network was being weird.
(I may have also borrowed his network switch.)
"Oh. that's cool but. uhm. WHY!!!?!?!"
"PiMark" (i think that's what it was called, anyhow. It was a benchmarking tool that would time your systems' time to calculate Pi to x digits. Or you could donate cycles to calculate... more pi.)
"uh. okay."... "clean up when your done."
