Haha. My friend has a "man cave" that is a little recording studio, too. He's not Orthodox, so no icon corner, but it does feature a dead/fried computer guts corner, for building frankencomputers out of (he's a tech guy at a major medical technology company, so he brings home all kinds of electronics junk that they would otherwise throw out). As far as I can tell, his wife likes it. After all, if all of his instruments and computer junk weren't in there, it'd actually be in the common areas of the house, and then there'd probably be a problem.
(They don't have kids yet, though, so I'm guessing there will be a massive sell-off of a lot of this stuff in a little while...hellllooo, cheap guitar amp!)
