I used to build my own PCs... and actually had one of the first water-cooled, overclocked PCs around. I ran it at over 4Ghz, and this was back in 2001... but alas, I do not have the time for that fun anymore.
In the Mac vs. PC ads, Apple bills itself as the antidote to Microsoft. To love Apple wasn't to sell out. It was to buy in. Most people use PCs, but Apple has the mindshare.
