It reminds me of someone I spoke with in the mid-late 1990's. He had a Pentium 1 system, which was rather desirable back then. When he went to demo and gaming parties, he was afraid it would get stolen, which is why he had stuffed it into an IBM XT case. Not because it was a cool thing to do, but because in the mid 90's nobody would even bother try to steal an old XT, seemingly terribly outdated and lame. Things might be different today, but it all depends on the physical condition of the IBM XT.
