My neighbor at school has 14 full computer setups that are almost as good as his main one. Over 4TB of space distributed amoung them all (never has to worry about backing up).
Anyways, it's because he's rich. Invited me over for a LAN party, and I said, bring or don't bring my computer, jokingly. He said, "Oh yeah, you haven't been over before." I was shocked! 14 computers, 14-21" monitors. I wish my dad was a defence lawyer!!!!!
Peace,
